I have 2 of the Nvidia Shield TV (gen 1) boxes, one with the hard drive and one without. I updated both devices to the newest firmware released last week (5.2) and ever since the YouTube app does not save my watched video in the history. This has the effect of not updating my recommendations. Anybody know how to fix this?
Edit: Solved! Thanks /u/Dwansumfauk
Are you by any chance using pi-hole?
