*** FIXED*** Pixel Fold
**Edited update to post at the end**
After an hour of searching and watching a few useless videos I realized the problem. I tried all the common sense things, clearing the cache, cleaning the storage and restarting the phone with no fix. Even made sure the phone was up to date. During all that I went to the Google Play store and searched YouTube and it had the "Open" button instead of update so I assumed it was up to date. I WAS WRONG. I kept searching and repeating the processes with no luck. After reading some of your post I decided to go back to the play store and search YouTube again. It popped up, same as last time but this time I tapped the YouTube logo, not the open button. When I did that it took me to the details and there it was...... UPDATE... Apparently it is only there when you click on the app in play store.... I also learned, for future reference, the only place on the Pixel you can uninstall is in the play store. Hope this helps someone.
***Update to post***
When you open YouTube for the first time after this, it will automatically turn on smart downloads.... So make sure to disable this if you don't want it because I saw it was trying to download 10 + videos.
