Paid for Pro Not Received

I signed up for pro. I was charged. It shows on my credit card. The app will not acknowledge it. Seems to be a very common issue with this company. Are they hoping people won’t complain to get what they paid for? I don’t understand how you do business like this.

Good concept bad execution

I’ve tried this app multiple times and it just isn’t that good. I don’t have any suggestions or answers but the app is more annoying than anything. Would rather just use Google if I have questions or need to figure something out.

Need help

I first subscribed with a yearly subscription and when I tried to add a 2nd aquarium it kept telling me I needed to subscribe. I checked in the App Store, my bank, and my iCloud account and all showing I was charge and indeed subscribed. Now after waiting a week after submitting a ticket with devs. When I try to login I keep getting, “type ‘Null’ is not a subtype of type ‘num’ in type cast”… so I went to iPhone storage and offloaded app and reinstalled and reloaded and it’s still not working. Can a Dev please help.

Paid for premium but it doesn’t work

When I first got this app thought it was absolutely fantastic and I still do think that it is a quite a great app for people using aquariums. However I have paid for the premium version and sent countless emails to the email addresses that are provided as well as the support team through the app in regards to what’s happening I seem to have a glitch and I cannot use any of the premium features even though I have paid the $59.99 per year to use this app. I didn’t want to have to write a review to potentially get a response out of the app creators but hear I am.
