Have to clear cache every time I leave the house. (Chromecast)

[Crizpy]

Hello.

I'm having issues with chromecast dissapearing in 'devices'

I have to clear the cache and log out of spotify every time I leave the house/ get out of range of the local wifi.

I have tried reinstalling and removing 'offline playlists' in my account.
I have also unplugged and upated chromecast.

I have all the latest firmware.
