Hello Ernesto,
My name is Joanna, I’ll be happy to help you out today.
I'm sorry that you are experiencing this issue, please try the following steps for troubleshooting:
- Turn on and off the device
- Uninstall and install the app
- Clear Cache
Clear Teams cache in Windows
If Teams is still running, right-click the Teams icon in the taskbar, and then select Quit.
Open the Run dialog box by pressing the Windows logo key +R.
In the Run dialog box, enter %appdata%\Microsoft\Teams, and then select OK.
Delete all files and folders in the %appdata%\Microsoft\Teams directory.
Restart Teams.
Please try to access Teams on web to check if you will encounter the same issue.
Let me know if this doesn't work or if you need further assistance.
Thank you
