Hello @PabloBarba 

Could you verify from the Teams Admin center that the Shifts app is not currently being blocked? 

1: Login to https://admin.teams.microsoft.com/

2: go to Teams apps > Permission policies and verify that no apps are currently blocked 

3: Go To Teams apps >App Setup Policies and verify that Shifts is displayed here as well ( sorry that the admin center in the image below is in Swedish ) 

If you've verified everything above and still receive this error please let me know

Kind Regards
