I've had my WiiM amp since early January so a long time user but this is my first post. Like many others I've had problems with a USB drive being detected/scanned, and ticket #500269 refers. As part of WiiM's investigation I was given some new firmware (5.0.606745) to try but this made matters worse. Since then I've been unable to install any new updates, and despite chasing (19 days ago), I've heard nothing since. Help please.
