I'm not sure why it was decided that the mobile watchlist view needs to be so different from the desktop one, but it was a poor one, frankly. It defaults on first load to an alphabetical view, meaning a wasted click in getting away from that. Then for some reason it shows multiple (how many? Who knows) edits to individual pages, instead of the most recent edit to each page. Maybe some people want that; fine. Make it an option. I just want a watchlist that matches the functionality of the one I've been using for the last 12 years. Is that so hard?
I'll keep switching back to desktop mode until this is fixed.
