Teams deep link can just only launch the teams app but can't open a chat.

Question

According to this document ( https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/deep-links#deep-linking-to-a-chat ),

I attached this Anchor tag ( <a href="https://teams.microsoft.com/l/chat/0/0?users=XXXXXXXX@YYYY.co.jp"> ) on my developing Application

so that our customer can easily open and start Microsoft Teams chat with certain person from our application screen.

The problem is that

in using mobile device ( iPhone8, iOS 14.4.1 ) ,

if teams app has not launched yet,

the teams deep link only launch the teams app

but won't navigate to a chat screen with desired user.

( Instead, it just show the last screen before teams app were closed. )

※In contrast, if teams app has already launched, the teams deep link succeeds in taking user directly to a chat screen.

※When not using mobile ( = in PC ), the problem above won't happen.

I hope the problem to be solved.

Thank you.

@K.Yasuoka ( TRE ) - We tried to repro the issue. It is working fine at our end in both cases while Teams app is running in background and also while its not running. We checked it in IOS version 15.
