iOS 12.5.4 some apps showing updates available, updates will download but not install
iPhone 6, iOS 12.5.4, 20GB free memory, good WiFi, good battery.
Some apps auto update OK, but several updates download but don't install, still show update flags.
The apps fail to update, but they still work on the older versions.
Compatibility of update shows "works on this iPhone", typically iOS 10 or iOS 11 or higher for all these "trouble" apps.
Examples: Linkedin version 9.1.231, Twitter version 8.78.1, eBay version 6.25.0.
I have tried resetting phone, closing/restarting apps, tried using purchased apps (just showed UPDATE flag again and then failed to update).
I am afraid to delete app and try to reload in case the apps won't be usable.
This just started with iOS update 12.5.4 and all say they will work with iOS 12.
What to do?
