@theEnkil: There are no issues on your theEnkil Plex account that would prevent signing in or account access. In fact, we show that you signed in to the account ~15 minute after cancelling the TIDAL renewal.
If you’re having trouble accessing your account, you can make use of our “Forgot your password?” feature to have the password reset to a known good value. You can access that at https://app.plex.tv/auth#?resetPassword
