Describe the existing feature/documentation

When searching I did find a slightly relevant issue #940
But for clarity I think separate one is better than posting in the old one

Describe your problem(s)

I suspect an app I have, well, "managed" rather bravely via AppManager is now misbehaving due to my tweaks (but it's an old, moody, janky app so chances are it's just naturally bad)

I would like to revert changes to this app particularly.

I did not make backups (of course :) )

So, question :

Assuming no backups done, and assuming the app does not hold critical user data I would be afraid to lose

Would uninstalling the app in question, rebooting, then re-installing it again revert changes done to that app by app manager ?

Should I also compliment that uninstall-reboot-reinstall cycle with doing a "remove all rules" in AppManager or would that be useless/excessive?

Additional context

When you reinstall an app, all but Intent Firewall (IFW) rules get reverted to their default state. If you had those configured, after installing the apps, open App Manager then open the app details page, navigate to Activities tab and click “Remove rules” from the 3-dots menu. If you do not see that option, try disabling one of the activities (or any other app components) and you should find that option if there are IFW rules in the system.
