0.23.1

Steps to reproduce the bug

1. Dismiss notification of video from subscribed channel
2. Mark the video as watched
3. Receive notifications of the same video over and over again.

Expected behavior

I expect just 1 notification of a new video from a subscribed channel. This should not return after it has been dismissed.

Actual behavior

I keep getting notifications of the same videos for months. I have marked them as watched, I have swiped the notifications away and I have tapped the notifications multiple times. A couple times per week I get the same notifications back.
