Hi Ryan,
Thank you for your feedback and updates. If this issue is occurred across multiple users in your tenant. The issue likely is caused at the tenant level for Teams. In this scenario, I suggest you can raise the service request in admin center with your tenant admin before this issue turn into degradation. The support can help you to check the backend data of your tenant.
At meantime, I have written a summary on this issue and send you via the private message. You can attach it when you submit the service request. It can help the support to quick narrow down this issue and resolve it for you. Sorry for the inconvenience caused.
Best regards,
Dihao
