Thanks a lot, that looks great! I'll test it asap and let you know if I need any help to set things up on the Play Console.

Updated the script to also upload the native debug symbols.

Hey, just wanted to check if you got a chance to test it yet?

Tested yesterday and this morning with some adjustments made by both @syntaxerror247 and myself, it seems to be working well now!

We can't fully validate just yet because the builds I have available (4.5.1-rc2 and 4.6-dev1) have already been uploaded manually, so I can't override them:

Next build is likely going to be 4.5.1-stable so we can merge now and finalize testing it in production. (Should be cherry-picked to 4.5 branch, I'll do it.)

I moved the location of the JSON key file to config.sh so users can name it however they want (like other keys in the root folder).

Thanks a lot! Great work 🎉

Cherry-picked to 4.5 branch.
