Collaborative scripts not working

I’m trying to script with my friend inteam mode, but I can’t see the scripts he makes and he can’t see the ones I make. I enabled collaborative editing and still won’t work.

I noticed that the grey dot at the side of the script should be green when someone’s editing it, but it won’t turn green even tho we edit it.

I hope I have explained my self good enough for you to understand. Any solutions?
