There are a lot of watch party style apps out there, watch2gether, netflix party to name a few.

However, I've not seen any that particularly shout about Android TV (or Chromecast).

Given the Covid-19 Public Health Emergency has us all social distancing, I'd like to watch, say, Plex, Netflix, YouTube etc, with a few friends. We used a Zoom call on laptops/tablets last night and verbally synced up at specific timestamps, and tbh found it hard because we could all hear the audio through the Zoom call. Perhaps we can't solve every problem there.

What I'd like is a service that:

1. Allows you to sync services and positions on Android TV clients (ideally not just them) for viewing.
2. If possible, also include some video calling support, be that directly or nicely usable with a seperate service.

You can assume that each viewing household has an account for the service in question (e.g. we all have netflix accounts).
