Don’t do updates!

This was a great app until I updated it. Now it won’t recognize my log in info and there is no Forgot Password or anything else to help, I’ve lost all my tracking and now need to find an app that actually has support.

Response from developer

Hi, Thank you for taking the time to share this — I’m really sorry for the frustration this update caused you. Losing access to your account and your tracking data is absolutely not the experience we want you to have. There was no data deletion on our side with this update. In most cases, this issue is related to an authentication mismatch (email, sign-in method, or cached session after the update). Please contact us directly at contact@reef-buddy.app with the email address you used to create your account, and we’ll help you recover access as quickly as possible. We do provide support, and we’ll make sure you’re not left without a solution. Thanks again for your feedback — it helps us improve Reef Buddy for everyone. — The Reef Buddy team
