Don’t hide top bar on iOS
When I am in the explore view I usually find myself have to work out the way to see the top bar. Where is my profile and filters for the explorer section.
It doesn’t seem to take that much of a space from my device, and I think I would prefer to have it fixed at the same point all the time so that I can use the options available there at any time without having to scroll down. Scroll up scroll down, scroll down.
I cannot see the justification for this behavior from the user experience perspective.
