This happens on my ipad 12 with OS 18.6, but not on my iPhone 12 mini iOS 18.5. The only solution is to exit Gmail, clear it from memory and restart the app. Then the same problems again. It seems to happen primarily when I'm filtering emails to show just one person’s emails (to cut thru all the unwanted emails). I've deleted the Gmail app and reacquired it from the App Store, but the problem persists. Same problem. Can you help?
