I’ll _probably_ follow up later and re-file this if appropriate. Or I’ll forget. The Uploads tab offers a sort option, and while many don’t make sense in that context, both Old and New do, but the sort is still “New” even when “Old” is selected. ### Steps to Reproduce 1. Have more than one page of uploads (or at least different time frames displayed) 2. Sort by old Expected: Sorts by old Actual: Sorta by new ### Technical Details Almost certainly N/A but iOS 18.7.2, Safari. ### Lemmy Instance Version BE: 0.19.15 ### Lemmy Instance URL hexbear.net
