🤖 AI-Generated Preliminary Analysis:

This Action.Submit issue with Adaptive Cards in Teams iOS is a known bug—several confirmed reports indicate the button renders but doesn’t trigger any action, even if structured correctly. It works on desktop/web/Android but is broken on iOS.

Workarounds & Checks:

• Try updating the Teams iOS app to the latest version, as ongoing fixes are being delivered by Microsoft.
• Avoid custom properties inside the msteams object in the data field; simplify your Action.Submit’s data:

  {
    "type": "Action.Submit",
    "title": "Summarize"
  }

• If using Input.Number, ensure you set min and max.
• Validate your card at https://adaptivecards.io/designer and ensure all JSON keys are lowercase.
• Limit to schema version 1.2 or 1.3 for best compatibility.

References & Tracking:

• GitHub Issue #5271 – Main tracking thread.
