DFU Progress not being reported and state doesn't transition to completed in release mode

[framinosona]

Follow-up of issue: NordicSemiconductor/IOS-DFU-Library#398

SDK version: 16
Bonding used: no
Library version: 4.9.0
Binding Library: https://github.com/Laerdal/Laerdal.Xamarin.Dfu.iOS
Device information (please complete the following information):

Device: iPhone 11
OS: iOS 14.3
Describe the bug
When the application runs in release mode, the DFUProgressDelegate does not get called and the DFU State also doesn't change to completed. The process does however complete and the device gets rebooted.

Logs
Because the application is compiled in release mode, the amount of logs I can provide is very limited. If anyone has an idea how to get logs in release mode, I will be happy to provide them.
