We have added a button of type Action.OpenUrl in adaptive card and its url as a tel link as given below.
"actions":[
{
"type":"Action.OpenUrl",
"title":"Call Mobile",
"url":"tel:+919090909095"
}
]
It was apparently working fine few days back but have stopped working suddenly. If we add any valid url as any like this,
"actions":[
{
"type":"Action.OpenUrl",
"title":"Call Mobile",
"url":"https://www.google.com/"
}
]
It works fine but our requirement is to open our phone app hence the tel link. We already raised the same issue from channel section, but from chat it was working fine earlier.
