SignIn button is not displaying

[lisitsyn-a]

Hi guys,

After typing connect the bot should display the SignIn button to authorize the bot in Azure DevOps.

Unfortunately, it is not working for some reason in Skype Desktop 8.41.0.54 as well as on Skype Android version.

However, I do see "card" content as part of previewing the message within "DevOps VSTS bot " contact in RECENT CHAT list.

Here is how it looks for me:

Here is an example of dialog started from the scratch:

Skype Desktop view:

I tried using webchat and the button displayed correctly:

WebChat view (available on outlook.com mailbox)

Probably the issue relates to BotFramework itself.

However, would not it be better to provide some fallback approach to get the Authorize URL?
