Yes, it works well. For apps. Go to qz.com for example on your iPhone (Android works fine). Try to scroll down and then use the bottom nav. See what happens?
I’m stuck with this “problem” now. Since iOS doesn’t let you use a bottom nav in the browser. A tap means, that you call the safari browser to appear and so my nav does not work. And users need to click twice.
So, what is your opinion on mobile websites? Still nav bottom as best option?
