I’ve got a prototype here:
This is a mobile prototype so it needs to be viewed on a phone to see the problem.

If you scroll down past the initial content there is a list of activities. Once you get to that point a DP appears and sticks to the top of the screen.
On my Android phone it works fine and you can continue scrolling
On an iPhone, it won’t let you scroll past that point.
Clicking on the filters CTA should make a panel appear. That panel is set to the back so it shouldn’t interfere with the scrolling on a touch screen. It is pinned to the browser but I’ve tried moving off the board just to see.
The RP file is here as well. If anyone can throw any light on it I’d be grateful.
