I think the swipeable carousel on mobile could use a little less activation distance to make it a bit more snappy. Compared to Instagram you sort of have to swipe your finger across the whole width of the screen.
For a couple of days now whenever I want to use Customise the are for the menu and the viewer stays empty, can't use it at the moment.
Tried this on Chrome/Safari on different machines.
Any ideas why this happens?
