For a while now, I've been testing an Android custom build game with my Samsung Note 9 phone (with debug keystore). I generated a release keystore and exported a release version of the game which was successfully uploaded to Google Play. Everything went well as a set of internal testers were able to access the game flawlessly.
Since it was my first, I hastily uploaded a new release (one day after) to include few minor changes in the game. However, my phone didn't install the new version, neither did the testers. Afraid that I might have done something wrong, I uninstalled the game and went back to Godot to do a debug build (one-click deploy). However, this didn't work either. Since then, I cannot debug the game using my phone (debugging using the PC still works tho and the game works flawlessly there). I tried using another Android phone and the debug still works. So I thought that maybe the problem is with my phone.
I consulted forums that talked about wrong uninstalls, clearing Google Play cache, adb tools to check installation remnants, etc but the game is not in my phone anymore. It feels like a phantom copy of the game is preventing me from reinstalling the debug version of the game (idk). From this, you might already guess I'm a newbie and I appreciate if you can dumb it down for me >.<
I feel like I did a rookie mistake with the Android custom build exports in Godot and I cannot figure out what it did to my phone. Since there are no forum questions that are similar to my situation, I thought that this must be a simple mistake. Any ideas?
