iOS Release Mode - difference in execution from Debug Mode (Background, Foreground, Lock screen)

[AuriDeimantasDev]

Hello,

I'm little confused over different execution in debug and release modes.

In debug - it works really well. Background, foreground and locked screen. However once app is ran in release mode - only foreground works. When app is in background or locked screen - callkit will work only once brought up in the foreground.

DEMO below demonstrates callkit behaviour. 5s after button is clicked, callkit will execute.

![Debug Mode]

![ReleaseMode]

Is this expected?

Minimal sample code below.

I'm having the same issue. Any suggestions?

Hey @AuriDeimantasDev, I've been running into this exact same issue for two weeks now. Have you fixed it?

[pasaninsharp]

Did someone find a fix for this?

[Essenbay]

How do you send VOIP notifications? PushKit provides SandBox (debug) and Production notifications, maybe you are sending wrong one? Device Token also maybe different from sandbox and production

i am also facing same issue
