oh, I noticed the rotation changes too! except I like the new version, it lets me play on my phone and charge it at the same time.
I have my phone locked to portrait mode so I can read on my side in bed and not have it "helpfully" rotate based on gravity. this used to lock the game into one landscape mode that put the charging port (and headphones port) downwards, but now it flips around so I can have the charging port up and available. I can see how that could be frustrating if it gets it wrong, though.
my tablet, an asus zenpad stuck on android 7.0, is locked to landscape and the game isn't rotating at all.
my phone, a oneplus 6 with the latest android (10?) will rotate between the two landscape options so that it's never completely upside-down (relative to gravity).
maybe it could be made an option? (but if I had my way there'd be so many options you wouldn't be able to find anything 😉 )
