Blank Screen on Various App Log Ins
when I attempt to log in to apps I have been using a long time (pc express for groceries, cell phone account) in my iPhone SE 3rd Gen, the log in screen no longer populates. This is happening on several different apps. Contact apple support who said it’s an app developer issue but it must be an iPhone issue, since I have been regularly using these apps for years and suddenly all stop working? All apps are subscription apps. Is there a setting on the phone that is somehow blocking the log in screen?
So far I have tried:
full factory reset
clearing browser cache
reinstalling apps after a shut down
changing language on phone
But nothing works. Software on phone is up to date.
thanks for any insights
