Unpinning an item in File Explorer isn't updating the jumplist (even when Files is open).

Unpinning an item in File Explorer isn't updating the jumplist (even when Files is open).

Also, just noticed that the quick access widget doesn't update either, will fix it

Fixed

Unpinning an item in File Explorer updates the jumplist but it hides recent folders from the home page.

Unpinning an item in File Explorer updates the jumplist but it hides recent folders from the home page.

I can't reproduce this, I don't know why it's happening

[yaira2]

1. Open Files to the home page
2. Open File Explorer and right click a pinned item in Quick Access
3. Unpin the item and notice that recent folders were removed from the list in Files.

I still can't reproduce it

It looks like you don't have recent folders at all on your device.

Oh sorry, misunderstood you, thought you talked about pinned folders. I'll try to fix it, but I probably won't be able to test it since I manually reset the pinned items a while ago

[hecksmosis]

This fix should work, can someone test it?
