Paid for product, no update... – Quick Math - Multiplication Table & Arithmetic Game Review

I have loved using this app and paid for one of the bundles from this developer. However, they have not provided an update, so it’s no longer compatible with my devices. Very disappointed to see that there is no update on a *paid* app. Will not be purchasing from this developer again.
