// Problem with Timer.publisher not work in navigation stack
//
// Timer.publisher *do not* fire reliably if the View is shown through NavigationLink()
// Work fine if it's not inside navigation stack
//
// The Pointfree Publisher.Timer do not fire at all when navigate in
// but start receiving timer when pop back out navigation stack
// run debug preview and watch print message in .onReceive()
