Hello Ritchie Verdonk,
Hope you are doing great. Thank you for the response and the explanations on this issue.
Further investigation reveals that we have had a lot of queries on this, and the team is now working into the matter. It seems evident that this is caused by the recent device updates. Could you kindly check and reset the device and see if it works afterwards?
If the issue continues, please contact Live Support. If you are an organization admin, you can submit a service request to report the issue using our online channel through the Microsoft Teams admin center. At the bottom-right side of the page, select Need help. A support agent can further connect with you remotely, for further troubleshooting and involve the backend team which might be needed for further checks.

Your patience and cooperation are much appreciated.
