Good day! We are having a problem with restoring purchases for old users who purchased the premium version of the app in 2015-2017 when the purchase price was lower. We use the standard recovery procedure, the ID of the purchase has not changed, only the price has changed. Could you please advice us, where can we find up-to-date information on this issue, or who can we connect to? Recently, the number of user requests with such a problem in support is growing more and more.
