When I renewed my contract a few months ago, I could no longer access WGN America or WE TV. I signed up for Premium TV, and these channels are listed. However when I contacted Comcast, I was told that they are no longer available for new subscribers. I wasn't new, simply renewing. There was no reason given as to why they still show up as available with Premium TV.
Today, 4/23/20, while reviewing posts in this thread, I found that both of these channels are available to me again!
I found it again last night - so happy! I have lost UP TV, WE Tv and WGN, and now all 3 are back. ID Channel and FE Tv are still missing - maybe they will come back again also. Thanks!!!
