Wireless Audio : Multiroom 4+

I use the app to connect to my Samsung MS750 soundbar and up until iOS 18 was mostly working but now it crashes each and every time I use it- if I delete app and reinstall it will work at first - for example I pull up IHeart radio app and select one of my stations it will play but if I minimize app and then go to open it up app quickly crashes and I can’t change station so frustrating - so have to delete app and add it back to phone each and every time hopefully someone can look into this

Long story short, this app has never worked properly even since the release of the first R1 and so on speakers. Numerous amounts of phone calls to tech support over the years... they didn’t even know what app I was talking about...🙄
Then toward the end (a few months ago) started saying they could put in a ticket to the developers but after five of those, no luck...
I’ve never had a good connection using the Multiroom App over WiFi. It would play a few songs, then freak out. Sometimes, it would log me out of connected accounts and then take forever to fix. Also, it’s not functional with Apple Music unless the music through iTunes is purchased. Meaning, no subscription for Apple Music can be played... most likely because of some stupid contract...
It’s literally a hassle with Samsung. I have a really nice tv that was over $3,000 when purchased. Worked great for a year, then they stopped updating the smart apps so it’s basically useless without a fire stick or cable...
After having my R1 speakers and this app for over five years, I upgraded to Sonos. Haven’t had an issue once!

As seems typical of Samsung, anything of important detail or critical importance to their users, just doesn’t work at all on iOS.
Say one of your wireless R3 speakers isn’t showing up correctly in this app. You need to reset the speaker and add it as a new speaker to get it to be part of the surround’s left or right rear set behind your Samsung sound bar. Well if your Mobile device happens to be the bastard child one from ... sush .. Apple, you my friend have chosen unwisely. Try and try and try as instructed to join the SAMSUNG wifi on the WiFi setup, then return to this app, and ... ... nothing. The app simply is braindead. Kind of like the decision makers at SAMSUNG, who believe that a great product is only worth launching, not worth maintaining and supporting, especially on that very odd Apple operating system.
To ANY iOS user considering getting anything of SAMSUNG accessory that may need to be run or configured by your phone - just don’t do it. SAMSUNG really seriously doesn’t care at all IF it works, and obviously never tests and maintains any of their products after the splash of initial release. Trust me. I know.
