iOS PushNotify demo - exception during method invocation/Internal server error

Dear Backendless Team,

After the entire complicated Apple certificate-aquiring procedure I managed to registerForRemoteNotificationsWithDeviceToken with PushNotify iOS demo app with success.

I do see my registered device in Backendless console, but I encounter two issues:

  1. Call to

backendless.messagingService publish

throws an “exception during method invocation”. I did not change any of the default parameter values.

  1. Publish Message from Backendless console results in “Internal server error”.

I should be very grateful for any hints.
