It is an on-going issue, but that was their acknowledgement 19 days ago, I agree there should have been an update by now, but you can't say there was radio silence. If you check the bug reports they're still giving the same work around, and it is working for some people but not everyone.
19 days ago this problem was a single case. Now the problem has become widespread. And the developers are still silent. And not only is it impossible to log in through a Google Play account, now there is also a problem with an EA account. You cannot import your main account and you are constantly thrown to a small account. Even after deleting and reinstalling the game, you cannot log in to the game like the Guest. Game drops you right in to the smaller account all the time
