Spotify glitchy with Echo devices

I use Spotify premium and have 5 Echo device from which I listen to Spotified music.

Is it me or is this combo glitchy as all get-out?

My “available devices” list seems random - names of devices change, some disappear from the list never to return, others go away and come back when, I guess, they’re good and ready.

I’m thinking the entire system needs to be re-set but I’m not really sure how to go about it.

Thoughts?
mmm
