Mention + onBehalf is not working in IOS mobile client

Brass Contributor

I sent an adaptive card from a bot that has user mention entitites and also uses the onBehalfOf functionality which posts the name of the user on top of the message -> "User J via botname"

That works fine in all cases on the desktop version. However on the ios client, the "User J via botname" is no longer rendered when there is a mention included in the card.

If I remove the mention entities, the onbehalfof is properly rendered.

As this is not consistent with the desktop I assume that it is a bug. 
Is this the proper forum to report it?

@jocsch-We are looking into this I will get back to you soon.

@jocsch -Could you please share the IOS/teams version and also share the screenshots?

I have two screenshots: The screenshot of the mobile version where the onbehalfone is missing (because there is a mention in the text) and a screenshot of the same message in the desktop client which includes the onbehalfof (just to verify that it is included in the message)


Is this sufficient?


Mobile (Teams Version 4.10.0 Build: (general) on ios 15.5):



This is the desktop version of the same message
