so first of all i have figured out how to get the remote feature to work, and it is throught that notification you were talking about, on my s8 sometimes after i open up bixby there is a notification that says spotify in the app name line and then the actual notification says spotify connecting... and sometimes once it does it says spotify connected to home. so once i saw this for some reason i decided to open up my spotify remote widget on my gear s3 and it worked! the thing is though i looked back on the notification and saw that the notifcation had changed and now it said spotify in the app name line and that my gear s3 is connected. so after about two days when i didnt listen to spotifiy on my phone for a bit the notification went away and i couldnt get the romote feature to work again. we need to figure out how to get that notifcation to stay in the notification drawer because it seems like itll work everytime now
you're right... now... everything makes sense... maybe samsung updates turn off this function by the spotfy app, to force us to use the native music player.. works almost well... it is very slow and miss some commands...so prefer use just one app and widget of spotfy.
As some others have mentioned, as well as me, remote control by JVC and Kenwood and BMW car audio units has also been broken since November, unless you roll back to that early version. This won't be a Samsung Gear or Samsung Galaxy watch only it seems.
I honestly can't believe there has been no official solution on this yet... or even any ACKNOWLEDGMENT. As people have already said previously, this is affecting... just about everyone, and has been going on for MONTHS. And, also like a lot of people, the "remote control" function on the Gear S3's spotify app was probably one of the biggest persuaders in my buying it... I really wish this would get fixed...
