UNO android app not receiving mqttclient subscribed topic

[LiftTrack]

Current behavior

Hi,

I am using MQTTnet in my Android app. I have created an Android application on the UNO platform. The application is working fine in debug mode but when I publish my app and run it on my mobile phone, I am unable to receive subscribed topic after installing "APK" file on my mobile phone. Unable to find out the cause behind it.

Steps:-

1. I am connected with "test.mosquitto.org".I am able to receive messages when I published anything under a particular topic.
2. In release mode or by installing the published "APK" file on my mobile phone, the app is not receiving published messages from "test.mosquitto.org".

Please provide me with a solution to it. Why my app is not receiving published messages in release mode?

Attaching a video for help.

Expected behavior

My App should work in the same way as it is working in debug mode. But after installing published "APK", App is not able to receive MQTTnet messages.

You may be hitting a configuration issue with the linker settings. Make sure to review https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/trimming-options?pivots=dotnet-7-0.

You may want to try and disable the linker altogether and see if it helps. If it does, you'll need to find the right linker configuration to remove some assemblies from the linker.
