The app crashed / a screen looks wrong. Tell me what you
were doing right before it happened, and your device model + iOS
version if you know it — that's the single most useful detail for
tracking a bug down.
Local multiplayer won't find anyone. Both devices need
Wi-Fi and Bluetooth on, need to be near each other, and need to have
accepted the local-network permission prompt the first time the app
asked for it. Check Settings → Sboogie → Local Network is enabled.
I bought something and it didn't unlock. Email me the
approximate date and what you purchased, and I'll help sort it out.
Nothing is ever lost — Apple keeps a record of every purchase even if
the app didn't apply it correctly.
I have a rules question or a house-rule suggestion.
Happy to hear it — email me directly.
