These limits apply on a per-property basis. If you need higher limits, you can upgrade your property to Google Analytics 360.
Collection limits
Google Analytics doesn't log events, event parameters, and user properties that exceed the following limits. For example, Analytics doesn't process the 26th user property nor does it process an event name with more than 40 characters.
