UI Builder Desktop Preview Not Working

I’m doing my missions in UI Builder, and when I click Desktop Preview is not working.


Been working this for 30 minutes already but I still don’t know why Desktop Preview is not working.

Hello @Jim_Karl_Dalde!

I just checked your application and the preview is working on my end:
