I have an app on F-Droid that is affected by this issue and thus moved to the archive (https://f-droid.org/wiki/page/de.mreiter.countit). Could somebody please explain in detail the steps I need to take to trigger a new build for this so it moves back to main?
What if the build fails (which I deem very likely for a 3 year old app)? Will the old APK still be available in the archive? If not, is there any way to check in advance whether the app still builds?
