I have been running this MusicCast app for about nine years, and it consistently has lag and connectivity issues. No other app for any smart devices have any lag whatsoever. None. Want to adjust the volume of a room? 75% of the time there will be lag. Want to skip a song? Lag city. Tired of listening to music and want to switch over to TV? Prepared to wait up to 30 seconds or longer.Absolutely terrible.The Yamaha MusicCast requires constant rebooting, and this is a *hard* reboot, achieved by unplugging the entire receiver. It's so bad that I have the receiver plugged into a Kasa smart outlet so that I can remotely reboot the receiver, something that I have to do sometimes three or four times a day.Guess what? The Kasa app >instantly< cuts off the power with zero lag. I have FiOS in the house, so my speeds are very fast. Also, I have an eero mesh system that is seamless for every other device that is connected to it, except for this Yamaha app. In no particular order, here is what I have connected my Wi-Fi, all of which work flawlessly: four Roborock vacuum cleaner cleaners, a dozen smart outlets, a wireless printer, three laptops, a smart stove, a smart Pet feeder, two Wi-Fi connected smart TVs, a YoLink hub system for power outages and water sensors, and at least five Ring cameras.I keep on waiting for Yamaha to fix their app, but, after a decade, I have lost hope. Sonos, help me...
