Just noticed that when I browse my Discourse site on a 7" Windows 10 tablet using the Edge browser, I don’t have the option in the menu to use mobile view. If I swtich to Chrome on the same device, the option is available. Due to performance reasons Edge is a much better browser on these cheapo tablets, though.
Also a side note that the writing mode of the desktop view does not really work with this configuration. The touch keyboard gets in the way and an iPad-like solution might be needed.
