Microsoft Edge and dropdown menu

Hi,
My current client has MS Edge as their default browser. They are a full Microsoft shop, using Surfaces etc...
They are experiencing problems with dropdown menu, they can't activate them. I was with one user and I hit refresh then dropdowns were now active.
I've been using IE (I know...) and never had any problems. I use Chrome as well without a hitch. I tried Edge and did not encounter the same problem. But there's been multiple users that uses only Edge that reported the problem.
Has anyone experienced something like this? Is there a way to solve this?
Thanks!
