Hi, I had a problem using NextCloud for the first time.

I integrated NextCloud calls into the browser of a third-party Windows application on the PC.

But the built-in browser for this application is not IE, Edge, Chrome, Firefox, etc.

After opening and logging in NextCloud, it seems that NextCloud identifies the browser as a mobile browser.

But there was no way I could change the app’s built-in browser, nor the built-in browser’s “user-agent.”

Is there any way to make NextCloud recognize it as a Windows browser?Can I modify it somewhere in NextCloud?

In the operating system’s browser (IE, Edge, Chrome, Firefox, etc.).The NextCloud is displayed and used normally.

No, that’s impossible. Such setting can usually only be changed on the client site.

This is the wrong way to display personal information. As you can see, even if the sidebar is stretched to its widest width, it is still the layout of the mobile browser

This is in the Firefox browser and it displays the correct layout

I was in the “lib/private/AppFramework/Http/Request. PHP” in this file, find some common browser the definition of “the user-agent”, I want to force change these parameters but doesn’t work

Thank you for your help!

Also in the file list, there are incorrect display places
