Perhaps a duplicate of #402

[akshetpandey]

Looks like it is, if thats the case, it should already be fixed in 4.6.0, let me release an version with that and see if I am still seeing it in wild...

[jegnux]

@akshetpandey as I said here, v4.6.0 didn't fix the issue for me.

[akshetpandey]

Yes, but that other ticket is still open and my crash report doesn't add anything new yet. I am keeping an eye on the other ticket and also releasing an app update with 4.6.0 today so I will know more soon.

[khopwood]

fyi, We still see this crash with 4.7

[pmiotto]

FYI, same issue on 4.7. Lots of crashes on iOS 11

@pmiotto The fix is in FirebaseInstanceID 2.0.8 which is the default for Firebase 4.8.0. Please update.
