Yeah I was using Aurora previously to get around having one. I read that its technically not as secure as Google Play has some extra checks in place to help avoid malicious apps. It convinced me enough to go the route I did.

But this is exactly the problem - getting randomly rugged with no appeal. 

Back to Aurora and Obtainium it is!  

 Also, if you want to put some trust into APK mirror sites like APKPure, Obtainium can install play store apps from there, and you can even bypass Aurora. But it's a little more risky.
