SmartThings iOS app update 1.6.85 (May 31, 2022)

sorry, my reply was to the post before mine. You may want to contact ST support to report the issue you are experiencing.

There is also an Edge Driver for Bond that you can check out:

Note: Edge does not work on the wifi mesh or connect hubs at this time.
