I’m having the same exact issue on a Fire TV but from regular shows in my continue watching.
Do you have a link to any posts or information regarding this bug I could take a look at @MovieFan.Plex ?
I’m curious now because dbirch took a look at my logs a few days ago fearing a corrupted database but didn’t see anything unusual.
It’s too similar a problem for me to not to wonder.
