I've noticed this too. I think it applies to most of their apps. I've had an issue since early April where a certain gmail account crashes the mail app (one account out of four only - it's not just me with this issue https://support.google.com/mail/thread/3994942).

The only fix is to remove all updates and revert to the original version of the app, and the UI experience is so much better. I'd forgotten how fast it was. I might just keep it like this.
