Thanks for testing. You confirmed what I thought, the automatic sign-in to Google Play Games services is broken. When the game launches, it should sign you in automatically. If not, then an icon for Google Play Games appears for manual sign-in. Neither is working. It’s like the Games services isn’t being triggered anymore like it used to, but I haven’t changed my Google Play Games code since I got it working a while ago.
I also debugged the APK as per your instructions and saw no errors for Google Play Games services.
Nepeo has anything changed with the plugin? The game was working perfectly for months, then all the sudden, it won’t sign in. This could have happened after a Construct update and I just never noticed, or perhaps something on Google’s end? But again, I never changed my code related to this plugin so not sure why it would just stop working.
I also tried always showing the Google Play Games icon so I could manually sign in, but it fails after you select which account. It never shows the “Welcome” graphic with your alias like it used to. So now manual sign in isn't working.
