Hi,
I’m trying to configure AppsFlyer and RevenueCat. And I’m getting following errors in the console:
[Purchases] - ERROR: 😿‼️ Error when syncing subscriber attributes. Details: The operation couldn’t be completed. (RevenueCat.BackendError error 0.)
[Purchases] - ERROR: 😿‼️ One or more of the attributes sent could not be saved. ["$idfv": "IDFV cannot be modified.", "$appsflyerId": "AppsFlyer ID cannot be modified."]
If I understand correctly, the AppsFlyer ID will be generated every time a user installs a new app. As users use multiple devices, I think this error will occur for every user who uses two or more devices. If this is the case, why is it shown as an error? Alternatively, how can I configure AppsFlyer and RevenueCat so that the AppsFlyer ID is unique? It seems impossible without IDFA
