corona has a problem with caling game center events

Hello everyone,

From a few days i have a problem with my multiplayer program.
When i create a match or post a move - Corona doesn’t call that events - but i see that statuses in Game Center are set properly.
This is not permanent sytuation - just sometime it works fine, sometime not.
I hoped in such a case calling loadMatchData - Corona returning me a proper statuses - but it doesn’t.
Event when i see that statuses are set properly in GameCenter

Maybe it is some kind of timeout’s problem - i see that sometimes before Corona called a event - it takes her a long time.
Do you have the same problem?
By the way - to confirm described problem i compiled and used Corona demo program - it had the same kind of problem.

Regards,
Dario
