Quick Question about Android


So I downloaded the app from the playstore and made sure the "market" was on the English/US flag. I tried logging in with details that I'm using on the PC but it keeps saying " ###Authenication/unkownPlayerName### "

Am I not able to carry on my PC game on my phone??


You should be able to. Provided you are indeed on the US market, you need to log in with the same details as usual from PC.
Keep in mind your password is case sensitive

Edit: On another note, I believe there is a "I have an existing account" button if you scroll down. It's been awhile for me but, pretty sure that's a thing.
