IMDB Watchlist UR

Since moving to Kodi 21 (Omega) my IMDB watchlist is not being imported from Kodi to my build app.  (using FEN and Umbrella).
Both have spors to enter my IMDB UR account # but when I go to “my lists” and choose IMDB nothing populated.  My UR is marked “public” in IMDB.
The process has worked in Kodi 19 and 20.
Any advise appreciated.
