iOS Teams App Doesn't display webhook message content after app update (app v4.15.0 / iOS 15.6.1)

Question

Hi,
After last iOS Teams App update to version 4.15.0 the messages received from webhooks do not show the message body/content any more. Only the webhook name appears.
This happens for new messages and also for old messages received before the update and that where showing the message content correctly before.

Started to happen after update of the Teams App. I did clear cache, also enable/disable developer preview, kill the app, restart iPhone, but no change in behavior

Iphone 7 - iOS version 15.6.1
Teams App: v.4.15.0

Anyone else having this issue?
Thanks

Answer 1

This is affecting me as well at the moment and has been for a few weeks: iPhone 13 mini, iOS 15.6.1, Teams 4.15.1. Other users in my tenant with different iPhone models are not affected.

Update: By the way, the issue might not be limited to markdown text. We send plain text and it is not showing up on my iPhone. We do use OpenUri actions, however.

Update 2: I opened a support case with Microsoft in Germany. Feedback is that it is a confirmed global issue that is being worked on by engineers with no additional information at this point. The support agent specifically referred me back here to this post for updates.

Hi @Crosby and @Jakob Keller

Nice to hear from you and so confirming we're not alone experiencing this issue. Thanks for posting on the thread....

In our case it's very critical because most (if not all ) of our integrations for NOC alerting (cloudwatch, grafana, ....) use markdown formatting, and now we only get an alert with the webhook name, but no idea what's going on,.

@Sayali-MSFT any news from Teams iOS App team?

Hi @Sayali-MSFT
A major issue for us as well. Here's the template we use for messages that show up fine in those running versions < 4.15.0, but don't show up in >= 4.15.0:
{
"@type ": "MessageCard",
"@Георгий Георгиевский ": "https://schema.org/extensions",
"summary": "Some summary description here",
"themeColor": "FF0000",
"title": "This is a red test: Teams Webhook testing valid card",
"potentialAction": [
{
"@type ": "OpenUri",
"name": "Click to view",
"targets": [
{
"os": "default",
"uri": "https://example.com"
}
]
}
],
"sections": [
{
"facts": [
{
"name":"Fact1",
"value": "Value for Fact 1"
},
{
"name":"Fact2",
"value": "Value for Fact 2"
},
],
"text": "Text for facts"
}
]
}

Answer 4

Not only markdown, i sent simple message and teams not show content
curl $url -H "Content-Type: application/json" -d '{"text": "Testtttt", "Title" : "test notification"}'

Answer 5

Updated fixed our reported issues!! Thanks.

As mentioned by @Jakob Keller on a comment of the first post (that i can't accept as an answer), the update of iOS Teams App to version 4.16.0 did fix the issues we reported (for us at least and for the known problems in this report)

Also Thanks @Sayali-MSFT
