Update is causing problem – Supra eKEY Review

The app worked great till the 4/3/18 update. When attempting to enter 4 digit passcode to open lock boxes, the app freezes when entering the 4th digit. So frustrating! Called Supra care and was told I needed to update my IOS 10.0 version? It says it's compatible with version IOS 6.0 and above. Please fix the update error!
