I have a Galaxy watch 6 classic and a Galaxy fold 5. I have been trying in vain to get the watch app to work and all it keeps saying is update the app on your phone but meanwhile both the watch and phone app or at the latest version. I'm going bonkers over here. Any ideas? Thanks in advance.
Here is what worked for me today: I uninstalled smart things from the watch using my phone and then installed smart things on my watch from my watch. This worked for both my wife and I (but we both have watch 4 and s23 Ultras)
