I'm using the "Save purchase for restore" feature in the hope that it will work with subscription plans because the "Purchases sorter" feature doesn't work at all (doesn't show anything or is disabled because nothing is found).

Although it does not completely work with the subscription package, sometimes it helps to receive the reward of the subscription package at the time of purchase.

However, I occasionally change devices resulting in saved purchase data being lost.

So, I hope to have a feature to backup and restore saved purchase data so that it can be convenient when switching devices or when reinstalling applications.

Also, please work to help the application operate with subscription packages.

Thank you.
