First my Chromecasts came online in the Home app but I still couldn't
cast. After several restarts of Chromecast, phone and network router I
could finally cast again! 落
Now my Chromecasts are online in the Home app again (went offline 9th of
March). Still can't cast to them!?I can tell my Google Assistant on
other devices to turn the TVs on and off so they are indeed online and
connected.
