Please help. I own eight Samsung speakers (R1, R3, and a few Sound bars). They are placed all throughout my home. Until recently I have been able to group the speakers together. Although it was very flaky, I would still be able to group them. Now they will not group anymore. All I get is a message saying to ungroup them and try again. No matter what I have done, they will not group together which makes them worthless for me. Please help. I have tried to reset my network, reset each speaker to factory reset and a different network and nothing. To me, the issue has to do with the app since it hasn't been updated in some time. Any suggestions is appreciated.
