I'm encountering the same (or similar) issue! The entitlement check passes, but when I get the user name it's blank. It used to work just fine, and then for whatever reason it no longer does.
I just made a thread about it here: https://forums.oculusvr.com/t5/Oculus-Quest-Development/Can-t-Get-User-Name-App-Lab/td-p/852599
I'm a casual dev at this point, but I'd first encountered this issue when I was doing the Oculus Tutorial through Unreal Engine a few weeks ago. At least two others experience my same issue, which presents when trying to access Guardian functions after checking to see if Guardian is Configured, which fails, despite passing the initial Verify Entitlement.
So, again, I am quite new to this but I think the "No Logged In user" warning is the larger issue, and I guess we wait for a fix from Oculus, as I assume this is a problem that only started appearing recently. The people in the thread I link to first noticed this in ~January, whereas that tutorial had worked at least as of 5/2020.
I suspect something about the Facebook account merge is the root cause, as I've tested as many other factors as I can consider, and even the Unreal's course instructor had not known what could be at issue.
