My SmartThings app on my Samsung Galaxy S9 recognizes I have a Kwikset door lock. However, it no longer has ellipses to add or delete door codes, which I used to be able to do on this ST app. I went to an APK website, and downloaded an older version 1.7.70.21, but still get the same Kwikset control that only allows me to lock or unlock the door bolt. Assistance greatly needed and appreciated.
Do you have Smart Lock Guest Access installed? If you don’t, go to the Life section and install it from there. You can add it as a favorite to show on up your favorite screen. From there, it show your lock status and when you open it, click on the down arrow in the upper left of the screen to manage lock codes for your locks.
