Thanks Brian, I will try that after reading the article.
Now I have another problem. I tried to play my music tonight but most of the tracks in Tidal album could not be played. It said it was unavailable. I tried to logout and login again. Forgot my password and changed with forgot my password request. After logging in, all my Tidal album disappeared in Roon.
I tried to log in to Tidal directly, and fortunately, my added Tidal album is seen in my collection.
How to link Roon back to Tidal?
