What am I doing wrong? Or - AM I doing something wrong?

You need to elaborate on the bug part. I own a Rivo myself and it runs here 24/7 without issues.
If you list them @Volumio can address them or we can help you solve them.

Rollout order, Bold has already been released:

  • Motivo
  • Integro
  • Primo 2
  • Primo Plus
  • Rivo
  • Rivo Plus
