I'm having issues with casting from phones to TVs (chromecast) and google hubs, when I open YouTube, sling, google photos or any app, it takes about 60 seconds to show up the casting icon, sometimes 30 sec, sometimes 2 minuter, sometimes it disappears. Then when I click on it, it takes another minute or 2 to start casting, it's random, sometimes it doesn't start at all. It started happening on its own. It was always working fine before. I have the nest wifi router (only one) and frontier modem. I tried resetting both modem and router, it didn't help.
