Room @Relation annotation with a One To Many relationship I have a POJO I'd like to get from the database which has a list of POJO's as a property. This, according to docs is doable via a @Relationship annotation. However, it's a one to many relationship where I don't directly reference the table/entity in question.

The problem is that I historically always signed all of them with the same key (same keystore, same alias). I wonder if it will be a problem for the Google Play Console. Once I enrolled one app, will I be unable to enroll the other apps? I am afraid to receive a...
