Sorry, I agree the back and forth has gotten a little confusing. Here's the TL;DR
-Story Mode and Event Modes don't work offline on iOS (I tested this on my iPad Air)
-Endless mode does appear to work on iOS, but it won't affect your leaderboard score since the game cannot verify it with the game server. Same with Android
Yeah, last I talked to the team they said they were working on an update but since then a few updates have come out for iOS and Android so I'm not sure what the hold up is. I'll need to ask around for an update.
Correct, Metal is only for iOS. I'll keep my ears open to see if we have anything planned that's similar for the Windows platform.
Ok! Sorry again for the request but could you let me know what device you're on again and if there are any other devices from your legion that are specifically having the issue? The more info I have the better when I approach the team. Thanks!
Correct, the 3rd issue is coming! I haven't seen the update submission go through for Windows yet but I'll keep my eye out for it. It's possible I missed the email so I'll double check!
