Good morning. I have a Teams account, email@example.com (unique user identifier 10032000A721803B) and I use Teams mainly through an App on an iOS device, as a student. Well I realized that for a month, suddenly, the "Calendar" icon, I don't see it anymore. Previously this icon was regularly displayed on my Teams profile, whether on iOS device or Windows App or Teams via the web. I tried to uninstall and reinstall the Teams app but the problem persists: the calendar icon is not displayed. I also tried to add it but it doesn't show me in "other applications". Can you help me? I can't find a phone number or email support on Teams. Please help me, thank you.
