Google Sync Known Issues with iOS
Here are the current limitations for using Google Sync on Apple® iPhone®, iPad®, and iPod touch® devices.
- Invalid Password Prompt. If you see an error message that reads "Invalid Password," it's likely that you'll need to unlock your account by solving a short CAPTCHA. Go to https://www.google.com/accounts/UnlockCaptcha and, if asked to, fill in your email address, password, and the letters in the CAPTCHA box.
- A CAPTCHA issue can occur when you have multiple devices, and one of them is configured with the wrong password. Reset all devices to use the correct password.
- If the problem continues, make sure you have followed all the steps in the setup article, especially setting Safari to accept cookies from visited sites (the default setting in iOS).
- A CAPTCHA issue can occur when you have made many changes to your mail, contacts, or calendar. As a result, you might need to set your phone to check for updates every 15 minutes. To do so, open Settings > Mail, Contacts, Calendars, set Fetch New Data > Every 15 minutes and switch Push to Off. If you require data to be pushed to your iOS device, consider downloading the Gmail app from Apple's iTunes Store.
- We support editing draft messages on iOS and in Gmail. However, these drafts do not synchronize across accounts.
- We currently don't support creating new mailboxes (labels) from within Apple Mail.
Workaround: create new labels from the Gmail web interface.
- When you use Google Sync, some Gmail actions might behave differently for you. For example, when you "delete" a message from your Inbox, the Gmail default is to archive the message and not delete it. To delete the message, select Enable "Delete Email As Trash" for this device in your Google Sync settings. See our complete list of how actions taken on your device affect your Gmail interface.
- Accept/Maybe/Decline page has a field to Add Comments, but changes you make in this field do not synchronize with Google Calendar.
- Attendee status changes might not sync. Under certain circumstances, when you're invited to a series of recurring events, saving a change for all events after accept/maybe/decline only applies the change to a single, selected event.
- Imported recurring events may not sync. If you've imported calendar entries from another calendar system into Google Calendar, you might find that only the first occurrence of the event synchronizes. In some cases, the event does not synchronize at all. Events occurring multiple times per month (for example "the first and last Monday of each month") are not accurately represented in the Microsoft Exchange ActiveSync protocol. Recurring events created within Google Calendar will synchronize correctly.
- Duplicate events can be created when changes are made across daylight savings time. This issue arises If you edit an instance of the recurring event after the first event occurs, and you remove the attendee and select Save for future events. In some cases, the iOS device doesn't correctly make these changes, and instead creates two separate event series that overlap by one day. This problem often affects events created in the GMT timezone when the series of events spans across the Daylight Savings Time boundary. For example, if you create a series of recurring events in August, and in December you change an instance of the series, the iOS device will show both the original event and the changed instance in the Calendar application.
- Contact field limitations. The iOS device can synchronize up to three email addresses. Phone number synchronization is limited to two home numbers, one home Fax, one mobile device, one pager, three work numbers (one will be labeled 'Company Main') and one work Fax number.
Incomplete contact information. If you have copied a contact from your domain's Directory to Google Contacts, only the email address of the contact will be synchronized with your iOS device. On the web, the contact entries you see result from combining information you have manually entered and information from the contact's Google Profile, a connected profile. The information from these connected profiles does not automatically synchronize to iOS devices through standard contacts synchronization.
Connected Profile information is available on iOS 4.0 or higher using Google+ for G Suite. If you're not a Google+ user, you can manually enter a contact's connected profile data into Contacts. Additionally, you could delete the contact from Contacts and then copy the contact from the Directory to Contacts on your iOS device itself, which will move the contact information to the device without issue.
Note: Google+ is now only available for G Suite customers, and it is no longer available for consumer (personal) and brand accounts.
- iOS Reminders. iOS Reminders do not sync to G Suite due to the fact that there is no equivalent service in G Suite.
- G Suite Issues? G Suite administrators should see G Suite advanced mobile device management.
