Hi teddybear,

I'm sorry for the inconvenience. Please send us a feedback ticket using the WiiM Home App. Our engineer will troubleshoot and resolve this for you promptly. Thank you for your patience and support!

Had a response from support with instructions to follow. They eventually worked after several attempts but it's still a bit flakey so will monitor things.
