Thanks for the further information. We've recently introduced an optimization on home screen and notification badges will turn into dots if app icon size is smaller than a threshold with the goal to make icon and badge look balanced. We've been monitoring feedback and keep working to refine, and would love to hear your thought too. Thanks for reporting!
Ok, I understand. I've set the homescreen to 5 columns and 11 rows cause with a 19:9 screen I have a lot of vertical space. What settings do you suggest me to have notification badge displayed as number again?
