I am not able to repro any ANR in our app. Before upgrading to target 12 everything was fine but after upgrading to 12, many ANR are reported on firebase crashlytics.

    ANR 1:

    main (native): tid=1 systid=32245
    #00 pc 0x9fc58 libc.so
    #01 pc 0x1663c libutils.so
    #02 pc 0x16520 libutils.so

These ANR are mainly reported on Android OS version 11 and higher. Does anyone face same issue?
