I haven't seen this one mentioned before, and nothing pops up when the message is thrown into a search engine. When I go to update apps (either singly or "Update All") I receive a pop-up stating, "This discounted price is only available to customers who own a previous version of this item. To purchase this item at full price, click Buy." Clicking "Buy" does not do anything but return the pop-up. Clicking "Cancel" does not do anything but return the pop-up. After several clicks, the App Store main menu returns and the notification that there are apps to update remains. FWIW, I'm running an iPhone 8, with iOS 12.4 Anyone get, dealt with, or solved this issue?
