I have Infuse Pro 8.3.8 on an iPad with iPadOS 26.3. When I hit the triangular Infuse icon at the bottom of the screen, I get a Home Screen and the top horizontal line of videos appears to be the videos that I am currently watching. Many of them I can delete from the list by long holding on the video thumbnail and then pick “Remove from Watching”. However there are others (not just a few) where the list has only “Add to Watching” … which moves it to the front of the list and then at that point I can “Remove from Watching” but it doesn’t remove it, it simply puts it further back in the list. Feels like something has gotten corrupted… but I can’t seem to fix it.
Go to Settings > General > Up Next List > set to “Watching Only” and that should let you delete everything in the top row.
