When I want to upgrade an app installed by the Google Play Store and not available on F-Droid, my phone (Android 11) opens F-Droid instead of Google Play.
The standard upgrade of Play Store apps (and F-Droid apps) works normally.
I have a banking app that has to be replaced by a new app, so I have to follow a procedure provided by the old app, which tries to install the new app and F-Droid is started to do that instead of Google Play and that does not work.
@DwainZwerg , thank you for your reply.
At first I didn’t got the choice for F-Droid and searching for it did not work either.
I had looked here before
When searching in other settings, I finally got the choice for F-Droid in Setting > Apps (don’t know how I did that) and was able to clear then
