Hello Detective_Mc²,
I'm Ibhadighi and I'd happily help you with your question. In this forum, we are Microsoft consumers just like yourself.
From what I understand, you are trying to transfer files or videos on Teams, however, you keep getting a notification for update your system settings.
You may be told to update your system settings before you can transfer the files because your laptop or your device may not have the latest drivers, software, or permissions to communicate with each other. Updating your system settings can help resolve any compatibility or security issues that may prevent the file transfer.
Therefore, you may need to please update your system settings. To do that, you can follow these steps: • Go to Settings on your laptop and select Update & Security. • Select Windows Update and check for updates. If there are any available updates, install them and restart your laptop. • Go to Apps & Features and find Microsoft Teams. Select it and choose Advanced options. • Select Repair or Reset to fix any issues with the app. You may need to sign in again after this.
I hope this helps.
Best Regards, IBHADIGHI
