What you were expecting to happen, and what actually happened?
Tried to change my team before PvP match. Teams in the overview won´t load.
I recently gained a new slot because of VIP Lvl. Not sure if the problems started at this time though.
What are the steps to make it happen again?
Try to change teams before PvP.
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
Sure.
Try scrolling up in your teams list
