Hey @soumyamondal-accenture ,

It would be great if you could share the add-in manifest with us for us to understand this issue better.

[mobisw-msft]

The reason we had asked for the manifest was to ascertain whether this is a Hard block or a Softblock scenario, but it seems like this is reproducing across all types of OnMessageSend add-ins. Thanks for reporting this issue. This has been put in our backlog. Unfortunately, we do not have any timelines to share at this time.
