Hi @GinaDonovanGC,
I do not have an answer for you but I do not have recommendations based on Microsoft 365 LTI FAQ - Microsoft Support.
If we need assistance or have questions about this update, who should we contact?
You can contact Microsoft Education Support through https://aka.ms/EduSupport.
Additionally, you can attend Join Microsoft’s LTI Office Hours the 1st and 3rd Thursday of each month, 11am EST @ https://aka.ms/LTIOfficeHours.
The third Thursday of November is on the 20th so maybe you can attent that office hour if you still have a problem.
I hope those two options help you out.
