After filtering the people in a 'state' Nation during a data request fulfillment, I attempted to share the tags and save the filter. Despite refreshing the page three times, there was no response despite the fact that I repeated the same procedure. The page remained unresponsive, while the cursor and other tabs on the browser remained perfectly functional.
Thanks for reporting this issue. If you try the filter again and it is still not working please contact firstname.lastname@example.org. This specific issue affecting Thomas has been resolved.
