We are sending notifications using the ruby exponent sdk. We are finding that about 10% of notifications have a successful response but do not include a receipt id so we cannot then verify if they actually were delivered. About 5% of successful initial responses do not actually get sent when we check back with a call to “https://exp.host/--/api/v2/push/getReceipts” so if we don’t have ids we could be losing track of those messages.
Is this a known issue? Why would a successful send not include a receipt id?
