Smart lock is not working on my Android phone, also when you open smart lock setting in location and security it opens to a blank screen. I have searched this on Google and clearly this is a widespread problem across multiple devices and device brands. I have found one TEMPORARY fix, which is disabling smart lock in trusted agents, rebooting the device, then re-enabling smart lock in trusted agents. After doing this it works again for maybe half a day before smart lock is broke and opens to blank screen in settings once again. I need a fix. Im using a Moto Z3 (Verizon) running Android 8.1 with most recent updates installed.
