App for websites using app URI handlers doesn't work in Edge

Prabhav Mehra 21

Hi, I am working an App and followed the steps mentioned here https://learn.microsoft.com/en-us/windows/uwp/launch-resume/web-to-app-linking to create a web to app linking using URI handlers.
I can see the app in the "App for websites" settings and if I try to click the url from an external app for example Outlook, then app opens correctly but when I copy paste it in the Microsoft edge, it doesn't work as expected and just shows the web page. I also tried to run it from the "Run" program and that also works correctly. It's just the pasting link in Edge or opening link from Edge.

One of the docs issue also mentions that the Edge support is stopped now. Is it true and can we only open the app through other external apps?

I am using VS2019 and Windows 10.

Thanks.

Could you please tell me are you using the old version of Edge or the New Version of Edge? And have you tried this on other devices?

Hi, I am using Edge Version 104.0.1293.70 (Official build) (64-bit) and Version 105.0.1343.25 (Official build) (64-bit) and I also checked it on other devices and got the same issue. I also tested it with other apps. For example Microsoft Teams (on Windows 11) and the built in Microsoft Apps from Apps for websites such as Microsoft whiteboard or Maps with URL: https://whiteboard.microsoft.com, works the same. If I open it from email or other app, it will open the Whiteboard app instead of Web page, but when I open the URL in Edge then it opens a web page.

Do you mean the windows apps are not abled to be launched as well?

Have you checked the Edge setting - Settings > Cookies and site permissions, there is a "Application links" setting in the end of the list? Could you please try to test with that setting?

Yes the windows apps are also not launched when I enter the URL in Microsoft Edge (from the list of apps in the Apps for websites settings). But they do open if I click the from outlook for example.
I do see the "Application Links" settings in Edge and the "Automatically block or allow apps based on a list from Microsoft." is turned ON. And I see a list of links there, but no Microsoft apps such as Teams. But it only says that the listed apps will open automatically, in other cases we will ask permission. So it should work regardless of that.

In another issue I can see it says not supported for chromium Edge, which is the latest one being used https://github.com/MicrosoftDocs/windows-uwp/issues/2573.

@Prabhav Mehra I'll need to check this with the team to confirm whether this is the reason. There might be some time delay. Thank you for your patience in advance.

@Prabhav Mehra I've talked with some browser engineers but them can't confirm this in a short time. So I'm waiting for a response about this as well. I'll update here once I got the result.

@Roy Li - MSFT Any updates on this? The issue has been a high priority now and reported multiple times by the customers. Any chance the priority can be escalated?

@Prabhav Mehra I've shared a sample with the team and asked the updates about this issue. But currently there is no more information that I could share about this. If this is a very urgent issue, you could consider opening a paid support ticket at MS Support. You will get 1:1 support on that. Select Developer Tools -> Windows UWP Development -> Windows 10 Universal App Dev in the support page and you could contact the team. Please kindly note that your support ticket will be free if it is Microsoft's issue.

Hello,

Welcome to Microsoft Q&A!

I got the response from the team. There is likely some underlying integration between the OS (possibly ShellExecute) and Edge that made this work. But now, there have been many changes in both UWP and Edge. It's hard to find where has been changed. It will require a deeper investigation and resources beyond a normal forum case.

If you want to get more information like a solution or a conclusion about this issue. Please open a paid support ticket at MS Support. You will get 1:1 support on that. Select Developer Tools -> Windows UWP Development -> Windows 10 Universal App Dev in the support page and you could contact the team. Please kindly note that your support ticket will be free if it is Microsoft's issue.

Thank you.
