Adding a second account to Quest 2.

I have my kids profile as an owner for a Meta Quest 2. I have been trying to add my profile to the Quest as an additional profile. I've tried multiple ways, multiple times and have been unsuccessful. If i attempt to send a code to the email I use for the account, click add profile, it gives me an error that says, "Device missing owner - The expected owner for this device is missing". Even though it has 'Add your profile to XXX headset' right in the email, so to me its recognizing the headset account holder. 

If I try to add the headset to my profile through my account on the Horizon app using the 5-digit pairing code it also fails and gives me the error that the device already has an owner. I'm also having a hard time contacting support to submit a ticket through my account because my account isn't associated with a device. Has anyone run into these problems? Every time I deal with this Quest it becomes overly frustrating as nothing ever seems to work right with the system.
