I've wasted a day trying to get somebody to help me connect these R3 speakers to the WIFI - turns out that they haven't worked out how to make them compatible with IO13! How can they get away selling this junk if its not compaitble with the market leading phones of the day?? The customer service assistant told me to buy a phone with IOS 11 on it so that I can use the Multiroom app..... IOS11?!?!? It's 2020! Buy a new [old] phone ?? What kind of advice is that?!?!? Samsung - stop cutting costs and educate your miserable support channels.
Same issue Here on Finland. I Have M3 speakers on various rooms and now after Wi-Fi renewal, all is messed up. Samsung needs to sort this out. If not, let's go public and with bit wider audience.
