Hello Rable!
Thank you for reply!
1. I have no spases after commas in "Add product ID". Moreover, adding, requesting and purchasing works fine.
2. Thanks to BackendFreak I understood that should be used "Restore purchases" that "Has product" and "On purchase"
conditions have begun to work. But all of them don't work.
3. I did the test with three lines - the same.
4,5 I will read, and, if properly understood, will continue to fight
6. I will participate in your campaign.
