Details

When using adaptive card as a chatbot response, I set visible:false in the body but it is not working, still showing as default. For the desktop version, it works, but not working on iOS mobile.
Here is the example of my code style

{
"contentType": "application/vnd.microsoft.card.adaptive",
"content": {
"type": "AdaptiveCard",
"$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
"version": "1.2",
"body": [
{
"type": "Input.Text",
"id": "activity",
"value": "{\"attachments\":[],\"channelId\":\"msteams\",\"serviceUrl\":\"https://smba.trafficmanager.net/apac/\",\"conversation\":{\"conversationType\":\"personal\"}",
"isVisible": false
}
]
}
}
