I have two One SL that used to be paired as stereo and everything was working just fine.
I recently decided to separate them to have them in two rooms independently, and since then they both work as if they were on the left (or right, I don’t know) channel of stereo, instead of being mono.
I tried resetting both of them but I get the same result.
And they work perfectly in stereo when I recreate the stereo.
Any advice ?
