Same. Apparently it says this on the bottom of the integration guide, which I did not read all the way to the bottom until now. My employee hates the new integration & we have switched back.
Thank you so much for your posts, comments, and feedback about this. This is something that our team is aware of and working to fix. I do not have an ETA to provide but I will make sure this thread is updated when the fix is pushed.
Kind Regards,
