Teams update breaks cards
After upgrading to the newest version of Microsoft Teams for desktop we are receiving an unusual error in the new teams client.
On the newest version of the teams client we are getting the following message when attempting to read a message posted via the web hook api.
"Card - access it on https://go.skype.com/cards.unsupported."
On the older version of MS Teams I am able to view the message normally. There are no errors in generated by the API calls. I do not think it is related to the webhook or the api code. The message itself is a simple text alert message with a URL in the message referencing a support ticket.
Did support for cards/API created messages change in the latest version? Is there a new permissions setting that needs to be set? Thank you for your assistance.

I think I might have found what may have happened. If I remove the following line from C# code it renders correctly in both the old version and the new version.
Type = "message",

Type = "message", The JSON payload for my test case looks like this....

The message in the new version of teams
The exact same message when viewed in the old version of teams.
- Some more information.
This is the C# function that I am using to post the message to the web hook end point
/// <summary>
/// Send a message to teams group
/// </summary>
/// <param name="heading">Message Heading</param>
/// <param name="message">Message to send</param>
/// <param name="endpoint">End point URL</param>
public async static Task<bool> SendMessage(string endpoint, string message, string heading)
{
ContentAttributes content = new()
{
Type = "message",
Title = heading,
Text = message?.Replace("\r\n", "\n", OrdinalIgnoreCase) ?? string.Empty,
};
string contentJson = JsonConvert.SerializeObject(content);
using StringContent messageCard = new(contentJson);
using HttpClient Client = new();
HttpResponseMessage httpResponseMessage = await Client.PostAsync(new Uri(endpoint), messageCard).ConfigureAwait(false);
string response = await httpResponseMessage.Content.ReadAsStringAsync().ConfigureAwait(false);
if (response == "1")
{
return true;
}
return false;
}

Christopher_Lutz - We checked this at our end by sending an adaptive card like below and it is rendering fine.
