Hi,
When I use Brave browser or Chrome browser on my Android Poco X6 PRO phone, the mobile ui has one issue and that is when the menu disappears.
This can happen when the keyboard gets used, but it can also be toggled.
However the button to get back to the menu in both situations is not possibe on the mobile ui, it won't respond or there is no button.
Version: 1.7.0 release 2
Device: Comet Pro
We recently released a dedicated GLKVM mobile app for Android that addresses many browser compatibility issues.
You can download it here: GLKVM Mobile App 1.0.0 (iOS&Android) Open Testing is Now Live! 🎉
I really like this app, but it can't be used locally so I'm stuck on using either a standalone cloud (which I don't really want), or web ui.
Are there plans for local ip too? 
We don't have any plans at the moment. However, I will submit your request to the R&D team for evaluation. Thank you for your valuable suggestion!
I saw the same with Samsung Internet on an S23 Ultra: sometimes the upper bar disappears and you can get it back only by reloading the page.
The Android app, at the moment, is too basic (and a little buggy) to replace the web UI.
I noticed that when I turn on the virtual keyboard the bug is unleashed as soon when I collapse the left sidebar.
Funny enough the overflow shows also broken because I can 'drag' the side bar to almost close a big horizontal scrollbar appears, but yeah.... the canvas keeps small, idd refreshes fixes it.
Hopefully they can fix it on the mobile ui.
The issue is easily reproducible with Chrome for Android by tapping on Collapse toolbar.
See the animation below:
But there are also other situations where the toolbar disappears and you cannot show it back, while not reloading the page.
I also am experiencing this on Chrome and Firefox (both on current versions).
I also can not install the app due to the KVM being local environment only (no tail scale and etc.) Would LOVE the web version to be fixed from this bug OR allow the app to search for local address (no cloud).
