We have a null reference thrown by Google Play Billing, with the following stacktrace:

Google.Play.Billing.GooglePlayStoreImpl.ParsePurchaseResult (UnityEngine.AndroidJavaObject billingResult, UnityEngine.AndroidJavaObject javaPurchasesList) (at <00000000000000000000000000000000>:0)

From our own investigation, it appears that the java purchase list is null and the store is commonly trying to reconnect.

Most reports also have the following log associated:
Google Play Store: Purchase failed with error code 'Error' and debug message: ''
And a null debug message isn't too useful to help track this sort of thing, but that might be best as a separate issue?
