The Magic Box - Wireless Carplay

Does anyone here have The Magic Box? It's a device that allows for wireless Carplay but at the same time allows for streaming of Netflix, Amazon Prime, YouTube, etc. I just received one today and thus far i'm not very pleased with it. If someone has one and can tell me if i'm not using it correctly or if these are some of the issues with it:

- Can I use Google Maps and YouTube at the same time? If i'm driving and wanted to have a video playing, will Google Maps override YouTube and still give me directions?
- Any success with downloading and watching ESPN events?
- I have tried screen mirroring, but it just pops up and then goes blank.
- The interface seems slow, is that normal?

Essentially what i've noticed is that it's just a OS that is in the box and everything that I do on the Magic Box is being done via an Internet Browser.

Thank you for any help. If some of the above is just how it is, then i'll trade this in for the Magic Link which is just the wireless carplay since my truck doesn't have wireless carplay.
