We have created a list in SharePoint Online. We're attempting to create a notification rule set that, for a Person or Group column (in which there are check boxes to select multiple people if necessary), when it contains a persons name, it sends an email to that person.
We can get it to work once or twice, but it keeps reverting to "undefined". Screen shot of the example. First two lines in the screen print have blacked out the people's names. Final line, where it currently says "undefined" previous had my name, and I was able to receive emails in testing; but shortly after, it updated. I've not been able to find a solution to this issue.
