I'm starting to use the revenuecat SDK to push subscriptions to my apps. I have an app that is currently paid and I would like to convert to the subscription model.
In IOS, I have implemented a check to verify the first version that the user was installed, and if this is paid, I can deduce that the user has already paid for the app.
My problem comes with the android version, since in the sdk of this platform I cannot find an attribute similar to that of IOS that indicates the version or the date of the first installation of the app by this user. Is there any mechanism to be able to perform this check in android?
