I recently purchased an Android tablet from Walmart. When attempting to install the Control 4 OS 3 app from Google Play Store the app "Sign In" button is disabled and grayed out. Only the "REGISTER" button is enabled. I've had my control 4 system for years and have several smart phones working well on the system. Have also installed tablets from Amazon without issue. All previous devices allowed "SIGN IN" to existing system without the need for "REGISTRATION". App 324.11.05 2024-03-14 Tablet using android version 11 Tablet Device Name: 100071483.
