FYI, got this working, so it’s not broken after all!

Once Elan confirmed that TIDAL should work on my Home User account, I did a couple of things to troubleshoot:
- Signed out of Plexamp (I believe that I had originally signed in using admin account and switched to the Home User account)
- Unlinked and re-linked my TIDAL account to my Home User account
- Signed back into Plexamp using Home User credentials (not admin credentials)
I’m guessing that #1 and #3 are the important ones here (I needed to sign in using the actual Home User credentials vs. signing in w/ the admin credentials and switching accounts to get into my Home User account), but maybe I needed to re-link TIDAL too. In any case, this works! Thanks, guys!
