I’ve been pretty lucky with my recent App Store releases. Usually when I submit my update before midday I could count on Apple’s sign of approval the next morning.
The initial Mac App Store release of Relax is a different story. It’s been in review since Friday and I haven’t heard a thing after that. The In-App Purchases could be to blame. Apple usually takes extra care reviewing those, except when they don’t.
Oh well, fingers crossed it gets approved soon.
