Apparently, I'm not alone here. I'm on a TCL TV, which is relatively new. Purchased within the last year.
The problem with the Roku TV app started about a week ago. Shows that aren't live go right back to the description screen. They simply won't load. "Live TV," on the other hand, will perpetually load and just get stuck at a black screen.
There have been no changes in my email, ISP, and also no VPN use. The only app affected is the Roku App. All other apps apear to work when tested.
I've read through a few forums an "Roku support staff" (official or otherwise) appear to be as useless as any Microsoft support forum. Nobody will admit to a problem; they just keep collecting people's device specs for whatever reason.
For the longest time, I have been a proponent of Roku and TCL, but that has changed in the last week. If Roku can't even admit to the problem after numerous months and numerous complaints, I'm simply not recommending them anymore.
I've done most of the steps to try and fix things and nothing has worked. If there's a magic answer, I'm all ears but, NO, you cannot have my device specs. That info hasn't helped you since 2022, it won't help you now.
