If Gmail is slow or isn't loading correctly, use the steps below to fix the problem.
Step 1: Check that you're using a browser that works with Gmail
Step 2: Check your browser extensions or applications
Sometimes extensions or add-ons you've installed on your browser or applications you’ve installed on your computer can prevent Gmail from working.
Try temporarily turning off these extensions and applications one by one, then using Gmail again to see if that solves the problem.
To try using Gmail without any extensions, open Gmail using your browser's incognito or private browsing mode.
Step 3: Clear your browser's cache & cookies
The steps above didn't help
If the problem still isn't fixed, check the G Suite Status Dashboard to check if there's a known issue happening on Gmail.
