On our Passbolt 3.1.0 and browser extension 3.1.0 dev/test system - the column sort for Username and URI dont appear to be working. The caret icon shows when you click on the title and correctly flips up/down when you click on it - but nothing changes in the displayed table, no re-sorting occurs. The Resource and Modified columns work fine.
Seems to only affect “All Items” “Recently Modified” and “Owned by me” views. If you select another view such as “shared with me” or a “filter by group” then all coumn sorting works.
