Hi,
I’m working with the Unity IAP and I’m tring to add a Loading Screen. It works. But as soon as a reload the scene. I get the error : MissingReferenceException: The object of type ‘IAPShop’ has been destroyed but you are still trying to access it.Your script should either check if it is null or you should not destroy the object. But the purchasing still works and without the loader screen stuff, no error.
At line 132, I activate the loader panel and at 242, I call SetLoadingScreen witch is at 220 to desactivate it.
Thanks
