Hi Alejandro,
Thanks for contacting us and sorry for the inconveniences,
Here are some possible solutions that you can try:
- Make sure your students have the latest version of the Teams desktop app or the Teams web app. You can check for updates by clicking on your profile picture and selecting Check for updates.
- Tell your students to reload the website tab in Teams by clicking on the three dots (...) next to the tab name and selecting Reload this tab. This may help to refresh the page and load the content.
I hope this helps!
Regards, Sola
