That works! Brilliant – I totally thought I'd tried that and found it didn't work (it only updated the the final state so changed, but only used one animation). Thank you. … would you be able to extend your answer to explain why the other approaches don't work – either do nothing, or only update with the final state?

I haven't analyzed your other approaches in depth, but you should remember that a view is just a structure and SwiftUI can duplicate it and reinitialize however many times it wants, so a subscription done in init could happen for some copy of TestView - not the one in the view hierarchy. Values have to be assigned to a @State property after init (or directly with self._prop).
