Hey Cheers,
You asked this quite a while ago; however - I do not see any answer, less so a fair and square one. And yet, in my 2020 LG 43UN7390ALEXA I have the exact same problem. I seems that LG moderators do not ever check - or do not care.
Worse: LG is so utterly un-intuitive that no matter if I finally made my FAVORITE list - I still had to spend HOURS on end to see, ask, check and re-check on WHERE to access that FAVORITE list.
Miss Google did not help either - for an upper-scale smart-TV = unacceptable
Hoping that someone has the same problem and found the way out of such a simple but grave problem.
Willy
