Question Ads and Play Games Services not working after change of package name

Hey,
I added Google Play Games Services, Google Admob and Unity Ads to my Android game. Tested it and everything worked fine.
Now I changed the package name of the app. There already is a new entry for this in the Play Store and I updated the resources file for the play games plugin in Unity.
But here is the problem, after changing this none of the plugins does work anymore. At least not in the .aab-file, in the editor everything works just fine. So if I'm in Unity, Unity Ads do still work and I still get debug-log from Admob, but when I build the .aab-file and release it as a test via Google Play neither ads nor Play Games Services do work.
What I noticed is that the .aab-file now is a bit smaller than before (not much but 2 or 3 MB), so my guess is that Unity does build the game without plugins. I have no idea how to fix this, does someone has an answer to this problem?
Thank you in advance!

Edit: Problem solved. Copied project to a new folder and resolved Android dependencies (which also worked in the old folder but did not solve the problem). That's it.

 

I'm having the same issue, can you please elaborate on what did you do exactly? did you create a new folder and copied the assets, library, logs...folders to the new one?
