1.iOS silent notification should be received on the iOS App using console or API mechnaim

Actual Behavior

Please provide a description of what actually happens, working from the same starting point.

  1. ioS Silent Notification is not getting delivered , I tried sending from both the console and the API both are not delivering the silent Notification (Normal notification is working fine from both mechanisms).

How do I know it’s not delivered ?

because if it gets delivered it will trigger a call to “didReceiveRemoteNotification” function in the AppDelgate… On the console I checked on the "Silent Notification " box of course and on the API I set the flag “ios-content-available” to 1 but still no luck in both cases … I guess there could be an issue in the configuration of APN server

I’ve investigated this issue and I want to clarify if this issue appears on the device running iOS 13? Do silent notifications work correctly on previous versions of iOS?


Hi Olha,

I’m not sure really …all my devices are ios13+ … all of them are not receiving
the silent notification

I can assume that this issue appears only on iOS 13+ because Apple made some changes in silent push notifications. And on iOS 12 silent pushes still work fine for me.
We are working on this issue, the internal ticket BKNDLSS-20675 created.
We’ll notify here when it will be fixed.


OK Thanks
