Intercom android SDK v 10.6.1 is crashing on the app launch.

Question

We are in process of supporting Android 12 and upgrading our app to use AGP 7+ for which we are also updating to JDK11.

Hey @nitin g13​!I think you were in touch with the support team on this if I am not wrong and mentioned that issue was sorted after you modified the proguard rules for :retrofit-dontwarn retrofit2.**-keep class retrofit2.** { *; }-keepattributes Signature-keepattributes Exceptions-keepclasseswithmembers class * {@retrofit2.http.* <methods>;
