I have had the problem of not being able to sign into the d2 companion app. When I sign in I get a long string of an error: {"error":"invalid_client","error_description":"Bad client credentials","error_code":4102,"parameters":[]} So after this I try use the login screen from the "trouble signing in?" prompt. This login always times out after I go to sign in. I have changed my password, still same problem. So then I deleted the cache, reset app settings, and deleted content database. Still same problem, nothing changed. I deleted the app and try to sign in again... nothing. I need some help here.
