Async loading/Callback on progress of load

Hello,

Question #1. I get a pretty big hang when some tiles that have been uploaded to ion are being loaded in. Are these loaded in an async manner as to not block the game thread? Anything that can be done to avoid this?

Question #2. When transitioning from one point on earth, to another, I’d like to implement a “loading” screen of sorts as to avoid the visible “popin”. Is there a way for me to know when the appropriate tiles have finished loading?

Thank you
