Yes! I have a solution. It's not one that will please anyone particularly. I ended up here because my system simply wouldn't work and I was going round in circles with routers, extenders, and everything else, not realising until I found this thread that the app had been abandoned. My solution was to put the app on my old Galaxy Tab S which also refuses to update beyond Android 8. Instantly the whole thing worked and I have proper surround sound once again. However, there are now two important points to make. The first is a point to Samsung. If you don't want to update the app that is your prerogative, but do so gracefully; tell end users and make the app open source so that it can be updated by third parties or volunteers. You can't complain that it may not function properly anymore as it doesn't now. The second is a general point to all manufacturers. I bought my system in 2016 and having 3 or, being charitable 4, years of function out of it is scandalous. In a world of increasingly scarce resources it is simply not acceptable to stop supporting hardware after such a short period of time. You are selling many internet connected (IoT) devices these days, frankly of dubious benefit - such as fridges and dishwashers. These have a 10 or 15 year lifespan. Are you going to render these useless after a short time as well because you can’t be bothered to support the software? This isn’t a trivial question but should be taken back to boardrooms of parent companies. There needs to be an agreed worldwide policy on this, as it’s pointless gloating about ecological manufacturing policies when your devices are crippled after such a ridiculously short period of time and condemned to landfill. The answer is not to point to other ways of connecting devices, incidentally; I bought my soundbar and rear speakers to provide good surround sound and there is no other way to achieve the purpose I bought the devices for; I can’t even wire the rear speakers as they have no ethernet capability.
