Microsoft Teams on Android can unintentionally prevent emergency calling

I feel android also has a responsibility to prevent applications from blocking emergency calls.

Below is the email from Google Play. I wonder though what is the mechanism where apps can prevent calling?

Hello,

You may have a version of the Microsoft Teams app installed on an Android device that may unintentionally prevent emergency calling (e.g. 911, 999, 112, etc. depending on your region) when you are not logged into the app. The issue is caused by an unintended interaction between the Microsoft Teams app and the underlying Android operating system. Please visit the Google Play Store and update to the latest version of Microsoft Teams immediately.

For more information on this issue, please refer to this Help Center Article. If you have updated the Microsoft Teams app after December 10, 2021, you can ignore this email.
