Firebase SDK crash on receiving broadcast intents

In a recent update we began seeing 2 crashes coming from Firebase. Neither of these crashes are reproducible, and they happen pretty infrequently, but frequently enough for us to be concerned. The first one appear 99% of the time on Android 7 (1% on Android 5):

Fatal Exception: java.lang.RuntimeException: Error receiving broadcast Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x4000010 (has extras) } in com.google.firebase.iid.f@96947cd

And this one comes exclusively from Android 8:

Unfortunately the Firebase SDK is obfuscated so I can't see the full context of the crash, but the exception being thrown is an NPE on a NetworkInfo object trying to perform the isConnected method.

These are the firebase libs we are using in this build:

api "com.google.firebase:firebase-config:11.6.2"
api "com.firebase:firebase-jobdispatcher:0.8.4"

We upgraded the firebase-config lib from 11.2.0 to 11.6.2 and added the jobdispatcher lib between the previous release and this new release where we began seeing the crash. I've searched around but haven't seen any existing conversations about the issue, if anyone has insight we'd really appreciate it. Thanks!

I got an official answer from the firebase team to the bug report I sent concerning this issue:

Yes, you are right. This is currently an issue from Firebase SDK 11.6.0 onwards.
Our engineers are currently working on a fix for this issue, but I can't share any details or timelines at this time.

In the meantime, I would suggest you to use the older version of the Firebase SDK.

You may check our release notes for any further updates.
