Created a shared channel in a team in my CDX 'Contoso' tenant, shared to myself and a few others in our company tenant. From my corp teams, added a tab to SharePoint Pages, chose Home, it prompts for my company account which I choose, then it gets an error Selected user account does not exist in tenant 'Contoso'..... account needs to be added as an external user in the tenant first. This does not seem like correct behavior?
Hey brkcanada can you please clarify if the shared channel is shared with members in other tenant or everyone is from the same tenant?
The Contoso admin shared the channel with me and a two colleagues in our corp tenant (same tenant). So only Contoso admin and Softlanding me, two colleagues.

@brkcanada Is this SharePoint home page in the site of the shared channel, or some other site? Adding a tab pointing at SharePoint doesn't grant permissions (in any channel type).

It is in the Contoso shared channel site. Issue arose when clicking the tab from Softlanding team app. I can navigate the site and content though (from Softlanding team) which is interesting so it succeeded inspite of the error when chosing my Softlanding account.
Hey brkcanada can you please file a support ticket with exact steps to repro and the error you are encountering.

So far my understanding the channel is shared between two tenants
1) Contoso tenant - Home tenant where channel was created
2) Softlanding tenant - Invitee tenant with which channel was shared

When you access the SharePoint site directly from Softlanding tenant it works but when you access it via a tab app it gives you an error
The following doc states that guest user can't be added to shared channel but in my lab, I was able to add guest user who has redeemed to shared channel, is it expected please? Thanks.
Guest users are not supported on Shared channels. Just to be sure when you say guest this user has (Guest) next to their name
