Swish (Wishlist King)

I bought wishlist king based on the recommendation of our devs in May of 2024. I singed up for yearly billing through May 2025 at the price of US$190 a year.
We just launched our store, and I wanted to check out the settings, and now all I can see is a screen that says, they changed their pricing to US$490 a year, which is more than a 250% increase, and I could not access any of the settings of the app I already paid for unless I agree to the new pricing. I reached out via email and Alex replied, and made things right.
