Tested auto playback on 5 devices and all worked as they should.
Mark this as fixed till you are forced to find and android 15 workaround.
Thanks
There is not workaround else I would have put one 
It’s either an Android bug they’ll eventually fix, or a doc bug and in that case it will not be possible anymore.
Here’s a video by Theo explaining it: https://youtu.be/UMiB5Z7n6Y8?si=nIlsXPy8VtcBobee
So, not trying to get out of my lane here, but just want to throw out what the Tasker dev is doing…
With every iteration that Google forces on him, and the app, the users lose some functionality. e.g., one of the last 'Targets", took away our ability to control Wifi and BT; we can’t turn them off and on any more.
What he has done is keep his app on the current Target ver on PlayStore, and then use GitHub to provide an executable, that for lack of a better term, “Backdoors” the Target, and gives us back our functionality.
It’s just a cat and mouse game, but this is what is working for all the Tasker users at this moment.
This only works up to the point where play protect tags the apk and they ban you for doing that and you loose everything for trying.
The risks are not worth it.
There’s already a ton of ways to loose the account for false reason and bot bugs, adding real reasons is not in my plans.
And typically does not change anything for the Google Drive issue.
