Hi
I'm having some issues with using push notifications in an app. It seems as if sending the push notifications fail once a while on iOS-devices. In the push logs I've sent 7 messages of which 5 went fine and 2 failed for iOS-devices.
They failed at 6th of december and then I experienced it again on 1st of february - in between I sent multiple successful push notifications.
Looking at the details it appears as if this mainly relates to iOS-devices. The two notifications that failed didn't reach any of my iOS users, but came through to almost all Android (apart from 3 devices in one push).
Are there any explanations as to why I'm seeing experiencing this?
I have around 500 devices registerred for the push notifications and only send them a few times a month, so I shouldn't be hitting any limits.
