From what it seems like they’re moving it from the bottom of the screen to the top of the screen. It shouldn’t cause a massive issue since nobody searches for you to videos outside of the home area anyway.

With the official YouTube app, you can’t actually browse for videos(not shorts) outside of the subscription tab or the home tab. So, this is just unifying it into the same area.

Sucks for muscle memory, but I do understand why they would make that change.
