"I just released a really important Apollo update that adds the ability for users with remaining subscription time left to decline an automatic refund. Devs pay refunds out of pocket, and this will be about $250K, so I thank you for your consideration. ❤️ Also, this update includes an amazing “Goodbye Apollo Wallpaper Set” for your phone, tablet, or desktop, created by outrageously talented Apollo icon designers. You can unlock the pack with a donation that helps with refund costs. 🙂”
You’re all good! I’m also an Ultra + Pro user and there’s no refund needed. Apple treats that kind of transaction as a one time payment. It’s only those who subscribe for a set amount of time (month or year) that are offered refunds.
