Long story short I originally was getting only the "Flagged Emails" list back from the extension even though i have over 20 lists in my app. I then used the Graph API explorer and confirmed the same - only the flagged emails list in the API response.
Now when I turned "Flagged Emails" on then off in the Windows App it stopped returning any lists at all. See below:
So clearly theres some issue with the actual API itself (maybe I have too many lists), but I thought it was worth creating this issue in case it would be better to use the delta endpoint instead?
