Hello, I will try my best to explain what exactly what it is I need.
I need to store user input data into cloud and make it so that devices running app can share those user input data with specific app users (could be a group feature, or allowing multiple devices to be logged into one ID to access the input data)
I know how to do the user input data part, but I am not sure how to make it so that those data can be interacted LIVE among devices running the app. Obviously only a user-specific devices should be interacted.
Thank you, my appreciation goes towards those trying to help development community
