A number of other mobile games were unable to launch expected updates today on the iOS store due to suspected violations of Apple's new store policies. Among those policies are that you must provide the exact odds for each individual unit or item available if you have the ability to purchase randomized tokens/loot boxes/etc. for goods in the game (which MPQ does provide -- although the game doesn't make it clear that every item in a vault has an identical chance of dropping), and that you cannot monetarily sell a bundle that requires daily logins to acquire -- which the VIP Subscription in Marvel Puzzle Quest does.

We have not seen an update to the software since Apple adopted the new policy, which may be why MPQ hasn't been stung like Fire Emblem Heroes, FF Brave Exvius, Alchemist Code, and others. Just wanted to throw out there that there may be forced changes to the VIP system in the future, and if D3 doesn't make those changes, we may not be able to get store-based updates to the game on iOS until they do.
