I find that the website version of Lyst often stops scrolling when I use ut. I have to refresh the page in order to get it to work again. This happened to me several times during my last use, and it's quite annoying.
Also would be good to have more filter options in the mobile app. E.g. I wanted to find a black t shirt. I could select t shirts, then short sleeved t shirts, but then there are no further filters that I can apply. I can do a search for 'black t shirt', but then that seems to give me both mens and womens t shirts.
