I’m running Monterey 12.1rc, and the latest Devonthink. Mail is throwing an error on startup when I enable the Devonthink plugin, complaining about the DeveonThink BigSur plugin.
Problem is that every time I reinstall the Plugin from Devonthink, it reinstalls the “Big Sur” plugin. I’ve completely removed the Devonthink plugins from mail, yet the Big Sur version gets reinstalled. Is there a Monterey plugin for Devonthink v3.8?
Seems like there were old mail plugins in several places. After deleting them all, a reinstall plugins from Devonthink got me working… as you say, still says Big Sur
