No iOS8 - for paid app? – Number Bonds: Addition & Subtraction to 99 Review

How can SDE does not have support for latest iOS? That too for paid app?. Update ASAP! I wonder how can Apple approve apps which does not work on latest OS and that too it's more than 3 weeks. There should be some refund policy for such I convenience for paid app!
