Casting to Vava

Is there any way to cast/mirror from a smartphone to the Vava? I have tried everything but to no avail. Surely if on the same wifi I must be able to mirror my phone? Thsnks.

wouldnt recommend vava operating system is buggy, just use a cheap google chromecast

I have Chromecast built into my Nvidia Shield but it won’t work with the Vava. Bizarre.
