Fast link slider

Good evening.
I am having the whoop 4.0 and I change my band. I want to change it again, but the fast link slider won’t move. I read the instructies on the website and did what the website was telling to do. I still can’t change my band . I already contacting support. Hope someone can help with my problem.
Greetings,
