I tried to save a very simple form configuration (I simply added one rule to set the value of a date-time field), but when I click the Save button in the config, I get the following error: “Authentication error: Try reloading the page and ensure you are logged in.”
I am definitely logged in to my SharePoint Online tenant. Not sure why I’m getting this error, and if I can’t save a form config, I’m dead in the water.
