First time sync fine, very short distance but it did, now it doesn't even find the lock on the app... locks function works but not with Bluetooth

I purchased 2 locks for my front door and side door, because my locks were getting worn out found these on woot for a great price and installed them and paired each lock to 6 iPhone 8’s pairing was pretty easy but I did have to cycle bt on/off on one of my daughters phone before it would pair, once it pairs you hit the s button and save it and that’s it. App allows you to cycle between multiple locks with personalized lock naming it shows battery life and shows you exact time that you used the app to lock and unlock the password part works fine and keys work fine so far very pleased going to try them out more and may add a few more in the future

Easy install and key pad works right away. However app directions have Bluetooth option which don't show up. Will revisit review in a month. If app fixed will give 5 starsUpdate: my app still on version 1.0No updates for almost 1 year

This application doesn’t work. It doesn’t stay open, when clicking to open the app it force closes immediately. The last update documented was three years ago, don’t even bother downloading until the developer provides a new update!
