Capital Games TeamHi CG_Meathead , it is not just that we cannot login through our mobile devices, in my case I cannot even log in through the PC client either! The PC client asks me to link first through my mobile device, which is something I cannot do!
I have two Heroes accounts, linked to different EA profiles. After using a couple of times the workaround to log in through the EA account, I can no longer unlink it, so I'm stuck playing with the secondary account. If I try logging through my main account, I get an error.
And, of course, as other users, I cannot use Google Play to log in to any of the accounts either.
Wait why were you unlinking them? That wasn't part of the steps for the workaround
