MS Teams: deep link inside adaptive cards [closed]

2 questions

1. I have the adaptive card with a deep link inside - https://teams.microsoft.com/l/chat/0/0?users= as [mention] (deeplink)

So sometimes when I click on the link why I get - "Something went wrong. Make sure you've successfully added the app."?

2. I create the adaptive card with OpenUrl action. Url formatted as deep link (https://teams.microsoft.coml/l/task/?url={webAppPageUrl}&height=large&width=large&title={title}&completionBotId={appId})

So inside the custom page (webAppPageUrl) I got authentication.getAuthToken() called by js script code.

Error:ExtensionTabService: getAuthTokenForApp: Failed with error - Definition not found

When I tried to change https:// to msteams:// it worked!But now adaptive card with OpenUrl action does not recognize msteams:// anymore.
