Recently installed DT3 (v3.5.1) on a new MacBook Air with Catalina. I am able to use the “Mail Rule - Add messages to DEVONthink” script in a Mail Rule to add a selected message to DevonThink. But the corresponding script in the System Script Menu (“Add message(s) to DEVONthink”) does not work: it is triggered, and the popup opens for selecting a Group", but when I click OK in the popup, nothing happens other than the popup closing. The selected message is not added to DEVONthink. DT3 has full disk access.
If I open the script in Script Editor and run it there, it works as expected, but not from the menu. I am having similar problems with another script I wrote for forwarding selected emails – works in Script Editor but not from the menu.
Is this a Catalina bug? Or am I missing some kind of permission/access setting?
