Hi! The watchlist selector for episodes (acquired, watched, downloaded) recently got a new design. In principle it works great because with a single tap/click you get to mark episodes as watched. However, on mobile, the episode will disappear and another one will be placed under the same location where the tap is happening, marking a second episode as watched. This happens even when taking care of doing a single quick tap.
I'm able to reproduce this in an iPad pro 2015, which is my main device. I'd be glad to test on some others if it helps.
Thank you!
