When I send an invite and my guests accept, activate and login to the app, the lock/unlock buttons do not work. The guest hits the button, it spins and gives an error that the battery in the device is low but I’m able to lock/unlock the bolt right there. This has happened to guests using iOS/Android on 2 difference locks at different locations. I run a short stay apartment rental business and bolt doesn’t seem to be doing what you promised. I need help here.
