Hi,

Getting a lot of crashes with this stractrace:

same for me, but looks like a duplicate of
#744

looks like there are a couple of use sites with
FirebaseInstanceId.getInstance().getInstanceId()
when it needs to use something like
FirebaseMessaging.getInstance().getToken().addOnSuccessListener(...)
if you're using a more recent version of firebase messaging

Sorry for the inconvenience. We have released v6.0.0 which no longer contains the Messaging feature so you should not experience this issue anymore. I'm closing this one now, please feel free to reopen if the problem exists.
