Poor show for a £400 speaker

Recent update gives connection issues. The app is advising no WIFI connection when started and no option to set up again. Speaker generally stops playing on Bluetooth after one song so you always have to restart it.
Please update the app and speaker firmware urgently or the speaker is being returned.

Action Voice II

The app works perfectly guiding you through the setup of the speaker, updating the firmware, and enabling Alexa. And great to have an Alexa speaker that lets you adjust the EQ. Got the Action II speaker up and running perfectly, and it’s a great sounding speaker!

Poor connection

Anytime I ask Alexa to play music, it’ll say ok but no sound comes out of the speaker. It seems to be a connection issue with the speaker app and Apple Music
