I can't get logged into the app either. We already had a premium account that we were trying to share, so I switched to family. We got the invite, followed the link, got the app downloaded etc etc etc but the app won't recognize either the new login or the old. I'm pretty patient but this has even me frustrated.
I downloaded spotify for the PC. Installed it....signed up...went to login into spotif and get does not recognize username or password. I reset my password 3 times also and was able to sign into my spotify account online but still getting does not recognize username or password when attempting to login into spotify.
*** Now I am a new user and after reading all these problems and complaints I probably will not sign up for premium if this is the average user experience.*****
I'm having the same exact issue. I reached out to spotify but their email told me to check the community posts which it doesn't seem anyone has found a solution. It must be something wrong on their end.
