What kind of Issues do you most get frustrated when taking subway/underground?

Hello uxers,

Our team would like to conduct the research about our daily subway experience, and thus come up with some proposals to make some improvements.

It would be great if you would like to take some time to review some frustrations you encountered when you taking subway/underground :slight_smile:

we will be appreciated it a lot :smiley:

Thank you & Best Wishes !
