Here is what i do.
I deleted the existing application, and format my SD card.
Then I create a new application inserting the balena-sound for raspberry pi 3.
Then I add a device choosing Development and ethernet and wifi.
I enter my credential for the network.
I download the file then flash it with etcher.
When I connect my raspberry pi inserting the SD card and an ethernet cable, it shows in the dashboard but will not download anything.
I looked in release and there is nothing showing up.
I do not see where you can select “Use an existing application instead”.
Thanks for your help
