I am setting up different routines to play particular Apple Music channels on my echo devices for certain occasions. I have been able to create the separate routines, assign them different command phrases, and get them to play on the speaker groups desired. However, I can’t find a way to set the volume in the routine.

The idea is to have different preset routines around the house for morning music, daytime music, dinner music, and get togethers, and assign each an appropriate volume level. Does anyone know how to preset the volume in a multi-room music routine? Thanks!

Nope. Amazon won't let you do multi-room via Bluetooth. I can understand why. There is latency involved when it comes to Bluetooth devices. And every Bluetooth device has a slightly different latency, some very low and some very high. If Amazon allowed you to do this, it would sound like your music is echoing all around the house.

We had the same problem and tried everything
 Finally what worked was "Alexa, stop meowing"
Good luck!

There are region restrictions when you take an Echo device from one country to another. What might be available in one country might not be available in a different country. This would apply to music, movies, and even some smart devices such as smart plugs, light switches, etc.

It is also recommended that when you take your Echo device to a different country, you should contact Amazon support to help you reset your Echo device to the new country. You can't do this on your own. Amazon must do it on their side at your request.

It might be something wrong with the network that connects the bulbs. Are they connected through Wi-Fi or Bluetooth?
My smart light bulbs from vont.com use a Wi-Fi connection, and I have never experienced any difficulties. Maybe it is because the Bluetooth connection is not powerful enough to keep all the bulbs working?
You should ask a professional electrician because these two bulbs can actually be broken or no-good right from the production site. It is always the same bulb, right? I must be something wrong with it, and you might consider taking it back to the shop and ask your money back.
