Share buttons disappearing (iOS 14.4)

[zamboknee]

Keep having share buttons disappear on me. For instance, in both Apple News and Flipboard, the share button for Pocket is now missing.
This has happened for other different buttons as well.
Why do these keep disappearing?

Hey! Not precisely sure why this happens but I've been experiencing the same since iOS 14 (didn't happen to me on iOS 12/13) and the issue appears on both my iPhone and iPad.

More often than not, I see the share buttons disappearing after the app has been updated but a simple reboot brings it right back.
