@Minion3665 The latest release of Collabora Office app 25.04.6.2 has the mobile UI on Chromebooks instead of the desktop UI.

This happened before about 2 years ago, but I can’t find it in [github](https://github.com/CollaboraOnline/online/issues), should I add this occurrence ?

Hello! Yes, absolutely, please make a GitHub issue about this…

We should probably prevent the Chromebook app having the mobile UI at all…

I think currently we still use the same detection as mobile (if you have a small screen and are on a mobile-like device, you’re a mobile device), but that means that if you open the app in a small window on a Chromebook it’ll be the mobile UI. I’d be curious to know what happens if you resize your window up before opening a document, my hunch is that you’d get the normal (tablet and chromebook) UI rather than the phone UI

Now in GitHub:

> \### Describe the Bug
> The latest release of Collabora Office Android App 25.04.6.…2 no longer uses the desktop UI on Chromebooks, it looks like the mobile or tablet view. This happened once before about 2 years ago, but couldn't find it in github. Collabora Online 25.04.7.2 displays the desktop UI correctly - you probably already know this :-) 
> 
> This was reported on the forum https://forum.collaboraonline.com/t/coffice-25-04-6-2-app-has-mobile-ui-on-chromebooks/4153
> 
> Tested changing it from windowed back to restored, and tested both before and after opening a document, no change.
> 
> Also tested changing the Android app settings at the top middle (Resize/Landscape/Portrait), this did not help either, and tested both before and after opening a document.  
> 
> Note that the app sometimes ends up with a white blank screen when making these changes, ...just in case this is related.

> \### Screenshot
