Before I knew about the issues with F-Droid, I installed quite a few apps from there, and now I'm trying to switch them over to Obtainium. It's mostly going well, but some apps fail with the error "Conflict [App Name]". From what I can tell, this seems to be because the apps use the same package ID on F-Droid as on other platforms, but use a different signing certificate, and I can't update the same app with a different cert.
Is there any way to clear the saved certificate + package ID? I tried uninstalling the app and rebooting, but that didn't help, and I can't find a setting for it and there doesn't seem to be anything useful online. Maybe I'm misunderstanding though. Any help is appreciated.
