Currently I'm creating developer products for my game. However when I go to add the picture it never pop ups.
In game I always get a square image of this checklist, hourglass image.
On the websites it just a 1x1 white dot shown as the picture.
Couple questions are what is the resolution of the picture when you're prompted for a purchase alongside this is there a wait for approval on the picture?
Roblox has been down for a while during this time and was struggling to upload assets so hopefully it may be working for you now, I restarted my computer and everything started working well for me.
