I'm not asking for official support from the app developer, just knowledge that they "happen to" work on an alternative Android-based OS. Which they should, if all the APIs they depend on are there (including the Play Services ones, via microG or whatever). If they specifically look for "non-blessed" Android variants and deliberately fail to work, that's a shame, but if it's an app I need, that rules out that OS for me, unfortunately. That's just the reality of the situation.
