Everybody that raided me is playing on a another app version yet it’s nowhere to be found. This isn’t right to be having these issues.
Here, too! If they’re on a version we can’t raid back, they shouldn’t be able to raid us!
I know it can be frustrating, but this always happens when a new update rolls out. It will fully resolve when they finish the roll-out and disable support for the old version. The best advice is to just be patient.
