Hi guys,
Today we noticed a weird crash in our Crashlytics dashboard:

Fatal Exception: java.lang.NoSuchMethodError: No static method newBuilder()Lcom/google/firebase/perf/v1/NetworkRequestMetric$Builder; in class Lcom/google/firebase/perf/v1/NetworkRequestMetric; or its super classes (declaration of 'com.google.firebase.perf.v1.NetworkRequestMetric' appears in /data/app/gr.androiddev.taxibeat-w4fVWIzh1AjrX8exoOlubw==/base.apk!classes2.dex)

🔥 Our current Firebase BoM is 29.1.0 which corresponds to version 20.0.5 of our com.google.firebase:firebase-perf-ktx dependency.

❓ Could it be a class between our different versions of the Firebase Performance Monitoring lib?

🙇 Thanks in advance!

hi @HarisHoulis , sorry about the late response. Which version are you using? We will be soon deprecating the code checkDecide from Mixpanel entirely so you won't be able to see this crash anymore.

Any resolution for this?
