This error appears to have no resolve other than to go in and manually update all the scheduled tasks. No logins prompts or other options other than cancel it seems.
Scripts are not loading either.
Seems there is some kind of compatibility issue with the XML. I may have to open every scheduled automation script to see if it's actually working or not since the upgrade.
This is bad. I'm going to have to walk away and come back because I have critical processes that are now non-functional.
