Firebase Performance: Retrofit network requests are not being logged

Using

com.squareup.retrofit2:retrofit:2.9.0
com.squareup.okhttp3:okhttp:4.4.0
com.google.firebase:firebase-perf-ktx (bom version is 29.0.4)

I'm unable to see any network requests inside the Firebase Performance network requests section. Custom traces work fine but the network requests are empty. I also cannot see any I/FirebasePerformance logcat logs suggesting that http requests are being logged.

The app uses a simple retrofit service to make requests which looks like:

    Retrofit.Builder()
            .baseUrl("https://myurl.com")
            .client(get())
            .addConverterFactory(MoshiConverterFactory.create(get()))
            .build()
            .create(MyService::class.java)

The OkHttpClient :

    OkHttpClient.Builder()
            .addInterceptor(UserAgentHeaderInterceptor())
            .addInterceptor(HttpLoggingInterceptor().apply {
                level = HttpLoggingInterceptor.Level.BODY
            })
            .build()

I have already tried the following:

• Been through Firebase's trouble shooting guide for this issue.
• Downgraded my okHttp version to 3.12.
