iPhone 11 Mail repeatedly not syncing with Gmail
My fathers' iPhone 11 mail not syncing with gmail. I uninstalled account and reinstalled and it worked. Next day not working again. I saw there was an update - so I installed update. Now it worked again. A day later it stopped working again. He has plenty of storage and he doesn't use a lot of apps - He's in his 80s. Does he need a new iPhone or is there anything else I can try?
iPhone 11 Pro
