Same issue. I haven't been able to login for the last 3 hours due to this never ending loop of the following 3 screens:
"Connection Lost. Your session has expired. Either another device has logged into this account, or it has been 24 hours since you last logged in." -> "Sign into Google Play" -> "Google Play Games: Select a Play Games profile"
I only play this game on my Samsung S21 5G Android Version 15 phone.
UPDATE: I downloaded the EA App and PC client of SW:GOH on my laptop and was able to successfully log into my account. Despite this, I still cannot log into SW:GOH on my phone as of now (6:20pm Central time).
