I have not seen any fabric events come through for builds of my app distributed via TestFlight. When downloaded through the app store (for the same build), those events do come through.
Is this because fabric detects whether the app was downloaded from the app store on device (and sends or not accordingly), or is it filtered server side.
I ask the question because I would like to understand what impact some new event tracking code will have on my app before I release it.
Mike from Fabric here. We don't use any logic to prevent data from being collected depending on the distribution method. I've seen this situation happen, most often, if a developer adds conditional logic to only enable Fabric in certain build types. For testing new events, trying things out locally is the best approach.
