The WiiM pro doesn’t appear in my cast to devices list in my Amazon Music app if I don’t enable Chromecast. Signed into my Amazon account. I can play music from it using the WiiM Home app. The Alexa app lists the WiiM device. The country of my Amazon account is AU, where I’m located. The WiiM FAQs don’t say anything else. Any ideas, please!? Just got this thing and it’s driving me crazy. Have I misunderstood something? I thought it was possible to cast from the Amazon Music app with Alexa Cast, not exclusively Chromecast
