Was great, until they updated it

Thought this device and app were fantastic, until they updated it. No longer works, AND they deleted ALL of my previous recordings. Called their customer support-she managed to (SLOWLY) suggest to me all of the troubleshooting steps already covered in the app...only new advice was that *maybe* changing the battery would make it work. Absolutely NO recourse to locate the now deleted recordings. I now have an odd, cumbersome phone case (that makes it IMPOSSIBLE to use the flash for photos unless I remove the case, due to interfereing glare) that is USELESS. Money and time down the drain, and ZERO support.
