I can no longer login to Disney+ on my phone (it previously worked fine). Disney+ still works on my streaming box (NVidia shield). I even logged out and back in on streaming box still works ok. I changed the password (via streaming box), logged out and back in with new password, still works. I can log into my Disney+ account on my pc.
When I try to login on my phone, I enter my email address and press continue and I get an error code 83. I don't even get as far as it asking for my password. Live Chat is useless since you never get anybody.
I just installed the Disney+ app onto my Xbox One console and it worked perfectly. no problems with log on so it is not an account problem.
