Hi man! I think I found a solution.
The constraint for the deletion was for the items to contain the word ācopiaā.
I typed ācopiaā into the search box filter in the App data tab so it filtered the things that I needed to delete.
Then I clicked on āLoad 50 more itemsā many times, until the page showed the 1000+ items.
I selected all the visible items and clicked on the Delete button.
It showed me an error after a while but it is still deleting, so I guess it is working. Even if I turn my computer off it keeps deleting.
If for any reason this stops deleting, Iāll definitely try that plugin.
Thanks a lot!
