I've got 2 nest audio devices paired in stereo mode for a better audio quality.
They were bought from different shops and they've got different cast firmware versions :
Left : 1.54.277099
Right : 1.54.279716
Sometimes they can not be seen as a pair from youtube music or spotify when trying to cast audio content.
Is the difference between the firmware versions the root of the above problem ?
How do I synchronize the firmware versions in order to have it the same on both devices ?
