I have several Denon HEOS speakers, AVR, AVRX Receiver, etc. Often (but not always), Spotify lists my Google Chromecast speakers but not my Denon HEOS speakers. If I turn the phone's WiFi off and back on, it finds everything. It does this on multiple phones. Once it sees them, everything works fine.
I am on Spotify Premium Family. Using Google Pixel XL (Android 9) phones. I live in Canada.
Can this be fixed? It's a pain.
