Trouble Linking Box

When I try to link my box account it says Unsuccessful Login when I clock Already a Box User. Any help?

I have the same problem but haven’t been able to see anyway of rectifying it  :cry:

I also have this problem, and cannot fix it. 

I even got a new phone, reinstalled the App, have ZERO External Services, and it still says I can’t login or remove a service (since there ARE none.
