As in like, web browsers on phones have an option to force the desktop version of the website or the mobile version. If you have desktop mode on in your phones web browser, it will always show you the desktop version. But if you have desktop mode off in your phones web browser, it will show you the mobile version.
I use Chrome on Galaxy S10+, the desktop view is always disabled. If you're not logged in, VGC knows you're using you're phone and gives you the mobile adaptable version of the website. The minute you login that's gone and apparently, you manually need to find some tiny clickable button at the bottom of the screen to get the adaptability back. WTF.
