Hey folks,
Sorry it appears there may have been a miscommunication, the double skull damage from the AI was affecting everyone, not only those playing on older devices. Sorry for the mix up!
Regarding players who are still having crashing issues on iOS:
It is quite normal for apps to close on mobile devices when too many are open or too many memory hungry apps are open at once, the operating system automatically closes apps running in the background to help the active app run more efficiently. So if you have a really good new phone with the latest operating system, you’re less likely to experience crashes on any app and even then, less frequently than older devices running older operating systems.
The key difference with this specific iOS issue we’re investigating is that it seems to only be getting reported by players with more recent iPhones and the latest versions of iOS installed - so that’s what makes it stand out to us all.
If you have an iPhone 5 that still runs the game KUDOS on keeping your device in tip top condition - mine already died 4 years ago! - but it’s your OS and device memory causing crashes 
You can try these steps to help run the game smoother but we may not be able to assist you make the game run better in this case we do try to keep the game optimised so it continues working on older devices but at some point it does become very difficult to keep the game running on devices the manufacturer no longer supports either.
If you’re in the group using an iPhone 8 or later model and your game crashes quite regularly even with NO apps running in the background (and I mean NO apps - I’m looking at you Discord, Facebook, Messenger and TikTok users!) then I would recommend sending a ticket to help us pinpoint the issue.
If you send a ticket through we’ll ask you to send through some crash logs for us so we can determine what caused the crash:

The information you provide in your tickets is being gathered and passed onto the dev team so we can look for similarities in the devices, OS version, accounts, gameplay patterns etc of the people who are affected by this.
We’ve already been receiving the requested crash reports from a few players so thank you very much!
