Tonight I updated to V 3.5.33 from 3.5.29 (I obviously haven’t been keeping up on the updates). I was required to sign back into Tidal but I was unable to, only getting the error “your OAuth2 client configuration is not correct. Please check with the TIDAL partner support”.
I was able to use Time Machine to go back to my older version and was able to re-login to TIDAL from 3.5.29, so it’s working for now.
I couldn’t find any way to step through the prior missed updates, thus I am unable to update past 3.5.29 and use TIDAL without additional assistance.
Do you have another web browser to try with? Like Firefox or Chrome? You need to copy the login link you have in Safari after you click on Connect in Audirvana and paste it in Firefox or Chrome.
