For me it doesn't matter what device I use to access the site. My laptop running windows 7 and latest version of Firefox, Chrome, or even the ever worthless Internet Explorer. My iPhone 7 is what I typically use; iOS 10.3.2 (most recent version). And FWIW - the "mobile" part of the site does not work nearly as well as the "full site" option.
If the admins used the forum like the users do, they would find the problems the beta testers are (the users) finding and we wouldn't have to explain everything so explicitly.
