Google Tablet appears offline on Home a while after docking

Hello everyone,

I own a pixel tablet with a dock and I have set it up on Google Home. Once I place the tablet on the dock it appears normally on my Google Home app, I am able to cast to it, generally it works.

However, I noticed that at some point after I dock it, regardless of whether it's locked or not, it appears offline on the Home app.

I can still cast to it and it will turn online, however I'm wondering if that's normal or if there is anything I can do to make it constantly appear online on the Home app when docked.

Thank you!
