Can someone explain what can happen that an app is listed here? What are Missing Builds exactly?
They are app versions still need to be build or failed and need to be fixed or disabled. If they haven’t be built in the current cycle they’ll be built.
Yes, that’s basically the description from the page, but I still don’t get the difference between the failed builds here: build - F-Droid Monitor
Does the fdroid buildserver with the update command also build the apps? Or is it some pre-build step which can go wrong?
