I am currently developing an app for a company from my university.
There should be 3 screens and the app should be controlled from all screens.
For example:
If someone uses the sliders to control the traffic light, this traffic light should be displayed in the other screen and should be changeable if necessary. You should be able to control the app from several screens and all screens should show the result.
You should be able to change the app from any screen and each screen should show the traffic light live.
@WarrenBelz Thanks for help in the past and sorry for link, but do you have a solution? Thanks a lot!
