Dear Marita TANNOURY
Good day!
Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand you concern with unable to see what teachers have posted in Teams. To narrow down your issue, could you please allow me to collect more details?
- May I know whether you have the same issue in Teams on the web?
- May I know whether you have updated the latest version of Teams Version update history for Teams app deployments - Office release notes | Microsoft Learn?
- You can try to reset the teams app and check if there is any difference.
- Type settings in the search box, and then select the Settings app from the results.
- Select Apps > Installed apps, and then type Microsoft Teams in the search box.
- Locate the New Microsoft Teams app from the results, select the More options button (...) on the right, and then select Advanced options.
- In the Reset section, select Reset.
- Restart Teams.
- You may have a try to reinstall Teams and check whether the issue still persists.
If the issue still persists, please kindly share me more information, I will continue to assist you.
Please note that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
Thanks for your precious time and your understanding would be highly appreciated. Have a nice day!
