New Teams Won't Load Website Tab

[ezybao]

Hi Guys,

In Teams (work or school), we have a private sub-channel for one of our departments. This department would like to use Microsoft Planner privately between them to keep up with upcoming tasks. For the "General" channel, I am allowed to add a Planner tab. However, when I select a sub-channel and click on "Add Tab", Planner is no longer an option.

As a workaround, I had added a Website Tab for this private channel, which was loading the private Planner of the departments via the (tasks office website) address. This method works perfectly in Windows and Mac versions of the old (Classic) Teams application. However, recently we've been promoted to switch to the new version of Teams and the tab does not load. I believe it should request me to login to get permission but the login page also does not load.

Windows Microsoft Teams Classic 1.7.00.6058 (64 bit) - works fine.

New Microsoft Teams Version 23335.232.2637.4844 - does not load.

Mac Microsoft Teams Classic 1.7.00.3856 - works fine.

New Mac Teams version 24033.812.2721.9190 - does not load.

There is a bar on top of the window with a small error that says: "You're viewing content from (tasks office website). Be sure you trust this site before using it. If the site doesn’t load properly, open it in a browser."

Does anyone know a solution?

Warm Regards,

Alican

Hi @ezybao,

I tried to reproduce your issue and the same error occurs for me too. 

I have tried to delete the cache, sign-out and sign-in to the new Microsoft Teams, but the issue is still there (Microsoft Teams-Version 24033.811.2738.2546., updated 18.03.2024). When using New Microsoft Teams on the web I am also having the same issue.

In the classic Microsoft Teams the issue is not there.

It seems to be global version problem.

Hi Leon. Thanks for trying 😕

@ezybao I've just had a similar problem trying to add a website tab that displays a list of group forms, using the URL I'd captured from the Forms page.
In Classic Teams it works perfectly - when the Forms page loads in the tab, the login/authentication process kicks in and can be completed, allowing the Forms to be displayed.
In New Teams, the locin/authentication process simply doesn't work. The only option is to click the link to open the Forms page in a web browser. Seems this is a deliberate feature in New Teams - Microsoft 'announced' it earlier this year (but it passed me by): https://techcommunity.microsoft.com/t5/microsoft-teams/teams-retires-client-ability-to-load-websites...

Hi @LynnProspect, thanks for sharing. I've been able to solve it by adding Planner as a separate Tab in New Teams. We're able to continue working this way.
