Same. I only use old mode for both mobile and desktop. It’s super annoying that about once a week they drop me back into their utterly awful mobile web experience. Then have to go back to settings and choose request desktop site yet again.

Most recently they’ve switched image galleries to using their new desktop design, so simply trying to view images often pops up this new and totally incompatible experience. Earlier today the left/right nav icons stopped working so I just gave up on trying to view those images.
