Zara

Unusable. The clothing dimensions are measured flat... How does that make sense? Why not use measurements similar to every other clothing store? I would have accepted losing personal time, ordering and then returning clothes that didn't fit me but I can't even buy them anyway since I go to checkout and there is a bug stopping me from advancing past the address entry because the screen just shakes as if it's opening and closing something in the background, multiple times per second. Unusable.

I hate the new design of the UI. I just want to see images at the same size when swipping. it's unnecessary to add other images below with smaller sizes. You create an app for shopping, not for social media.

A few years ago, this app used to be difficult to use. They've made improvements. Now, it's excellent. One bug or usability issue that exists today: I am not able to sign in with my account into the US store. But the Canadian store works for me. I'm not sure if this is a bug or a legal/compliance constraint.
