Ok so,
my app is fairly complicate at this point, but it works, on iPhone.
And it doesn’t on Android.
Here, the last step.
Why? No clue.
@Mark I think this is something for your knowledge.
The problem seems to be in that username result, which is just a join from 2 text inputs.
Everything works, on android, until that last step, that it doesn’t compute.
At some point I have to save some values to firebase, and iPhone does it perfectly, Android does it partially.
FIrebase rules are completely open to esclude other reasons.
Anybody any clue?
