Describe the bug
Controller hitting backend code twice, when clicking on adaptivecard button in MsTeams channel (mobile) and throwing error. At the same time its working fine in desktop teams and web teams clients.

I'm facing the same issue with Adaptive Card with MessageBack button while using Bot Framework Composer. We've tried of the same scenario with same adaptive card if the response processing time is less than 2-3 second then no issue but if the response processing time is taking more than 3 seconds then in Bot controller we're getting duplicate hit from MS Teams.

Hi @srinath555,
We tried to reproduce this issue again, adding delays in different parts of the process to force a retry behavior, but even using several adaptive card samples we didn't receive the duplicated message.
Additionally, the BotFramework SDK only distinguishes channels, not platforms, so it's not probable that an issue that only happens for Mobile Teams would be related to the SDK.
Thanks.
