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

Hi @Sayali-MSFT

Thank you for looking into it and sorry for delay in response.

I've re-done my tests, after updating teams app on iOS to minor update 4.15.1 and still don't get to see the content of webhook messages. With new tests, it seems related to markdown formatted messages. (Unfortunately our webhooks all generate markdown formatted messages)

For simple plain text, HTML format, the message is correctly displayed on the iOS app.
On MacOS Teams Native App and WebTeams, all messages (including markdown webhook messages) are correctly displayed. Did also confirm on Android they work as expected.

I'm able to consistently reproduce the problem with:

Teams version: 4.15.1
Iphone 7 - iOS version 15.6.1
I've removed the app, and done a clean install (after new version 4.15.1 came out) but didn't improve the problem..

I've created a new webhook on a channel, and sent those two (to keep it short) messages:

   ## plain text message: having content displayed correctly on iOS Teams App.  
   $ curl $webhkurl -H "Content-Type: application/json" -d "{\"text\": \"Hello World\"}"  
     
   ## markdown formatted message: message content is not displayed, only the webhook name.  
   curl $webhkurl -H "Content-Type: application/json" -d '{  "themeColor": "D74654", "text": "emoji tester: 👊 \n\n `backstick text` \n\n >`simple\nbackstick\rtext\n\ndouble n` ",  "TextFormat":"markdown", "Title" : "markdown test notification"}'  

• iOS Teams App version info:
  
• iOS TEams App channel message window. Note the creation of the webhook, the first message (text only) with the content displayed, and second message (markdown) without content displayed.
  
• iOS Teams App with detail of markdown message, still no message content.
  
• MacOS Native Teams App: displaying correctly both messages.
  

Final Note: This was working fine before update to 4.15.0 on the iOS App, and after the upgrade, all markdown messages are not showing the message content.

Hi
any update / news on this issue?

It's really annoying not being able to see the markdown message content on the iOS app.

We are also experiencing this bug for the same iOS and Teams app versions, but running on newer iPhone hardware (iPhone 13 Pro Max, iPhone 12 mini).

This does appear to affect all our Teams inbound webhook messages that include markdown text, as @bugre mentioned above. All Desktop and Web Teams content is unaffected.

Any updates regarding a fix for this issue on iOS?

Answer 4

Agreed. This is a major issue for us as our on-call team is unable to ascertain the nature of emergency alerts.

We submitted and escalated an official case to Microsoft via Pax 8 yesterday, although I fear it will go into a product team black hole…
