Teams on iOS not correctly supporting url schemes
When a Card is sent with the OpenUri action, the iOS Client says "invalid url" when sent "awbs://....." or "awb://...." which are valid URL schemes for the AirWatch Secure Browser. Other apps on the same phone work correctly and open the URL in the Secure Browser app.

This also applies on macOS. I tried sending a link to a URL Scheme URL to open a certain app to a coworker and Teams didn't recognize it as a valid URL (either through just typing the link, Markdown [text](url) syntax, or through the hyperlink creation GUI.
