Hi Justin,
We are still fighting to resolve this issue and stop any unnecessary requests.
Firebase Crashlytics is Google service and we have contacted them about this matter, currently we are in the waiting for their response.
I have inspected the requests and I can see no tracking data in it. It's just data about the app like package name, version etc.
Seems like these requests are only executed on upgrade of the app, at least this is how we could reproduce it.
We are still working on that, so please hang on with us a little longer.
Thanks,
Anton.
