I am trying to use the deep link functionality to direct users from our web application to a tab within our MS Teams personal tab application.
Using the documentation here: https://github.com/MicrosoftDocs/msteams-docs/blob/master/msteams-platform/concepts/build-and-test/deep-links.md#showing-a-deep-link-to-an-item-within-your-tab
I have crafted the URL
https://teams.microsoft.com/l/entity/4e9afe6e-9fd0-4893-899d-03fa732432b7/Dashboard
and this works fine on desktop, but the mobile applications this fails with the following message

I cannot see anything in the docs that suggest that these links shouldn't work for mobile apps - is this intended behavior or should the link work correctly across all platforms?

Hi @charliedavison currently, shareDeepLink does not work on mobile platforms. Please go through this documentation for more details.
Hi @Mamatha-MSFT, thanks for getting back to me, I'm not trying to use the shareDeepLink function itself, I'm just creating the url myself using the format in the documentation.
I assume that the urls shareDeepLink creates are the same as the one I am constructing though - is the limitiation then on the URL's themselves not working on mobile platforms as opposed to the shareDeepLink function in the SDK?
Use the following format for a deep link to tab
https://teams.microsoft.com/l/entity/<appId>/<entityId>?webUrl=<entityWebUrl>&label=<entityLabel>&context=<context>
Please try and let me know if you still persist the issue.
That is the format I have been using and is when I see this issue.

@Mamatha-MSFT sorry, reopened as closed in error, see previous message. Thanks
@charliedavison Could you please explain are you sending deepLink as a message or adding the same deep link URL into an Action.OpenUrl in cards and also Please share your mobile model and version details.
Sure - what I'm trying to do is create a flow where we can direct users to our web application to complete part of signup journey and then return them to teams.
So the flow would be -
User opens the teams tab -> Clicks signup -> We open the web application -> They complete signup -> We then redirect the user to a teams deep link which takes them back to teams -> User is able to login.
This flow works on the desktop, the teams app is successfully opened again back to the correct tab as configured in the URL: https://teams.microsoft.com/l/entity/4e9afe6e-9fd0-4893-899d-03fa732432b7/Dashboard
It is only on the mobile platforms where I see the error.
@charliedavison I am able to repro the issue. Will be raising the same as bug if it gets confirmed from internal team.

@charliedavison We have raised a bug for this issue, concerned team is working on it.
Hi @charliedavison, Could you please try to uninstall the existing app and create a new app. Make sure to enter correct entity ID https://teams.microsoft.com/l/entity/
Try and let me know if you still persist the issue.
