My issue is not specifically with wyze-lock, so feel free to move it to a better category.
Auto-unlock feature is okay on my phone. I shared the account with my wife. When she tries to setup the auto-unlock feature on her phone, everything seems fine but as soon as she leaves the setup option, go back to home or switch the app, auto-unlock feature reverts to “disable”. We tried to reboot the phone with no luck.
The Phone is a Xiaomi Redmi Note 11 Pro + 5G, android 12 and Wyze App is v2.35.0.
Try clearing the app cache on both phones in account > app settings. Then force close the app on both phones. Now check this setting on both phones, and set it to on.
