Please contact me by email directly so I can assist you. Hello DeservedReviews and thank you for your message. I’m sorry to hear that you’re having difficulties restoring the lifetime plan you got for free. The good news is there is a mechanism in all apps that is called “restoring purchases” you can use when you reinstall an app or install it on another device connected to the same App Store account. When you see the paywall in the app, scroll down at the bottom and hit the “Restore Purchases” button. Your lifetime plan will be restored if you unlocked it earlier. Please contact me by email if this doesn’t work so I can better assist you. If the solution works, can you please update this rating and review to reflect that? Let me know! Thank you, regards.
