I purchased the lifetime subscription for BYOK during a promotion a couple of weeks ago. When I click “restore purchases” in OMNIAI , I get a message saying that my purchase has been restored, but I am still unable to put in my key; OMNIAI still tells me I have to purchase the lifetime subscription. I have sent the developer two messages about this issue over the past two weeks, including a screenshot of my the receipt for my lifetime subscription purchase in the “my purchases” list in my apple account. I have not gotten any response. I will be lodging a complaint with apple next, to return the purchase price.
