Is stopped working some time ago. The image and audio quality have turned AWFUL,impossible to watch it.

But it works BETTER when I send a video from VLC or Soda Player. Much better but still fails sometimes.

From the phone the quality is also way better but also bad often.

I've got 600MB Vodafone fiber at home and 5G frpm the phone, the problem happens in two different Chromecasts, versions 1 and 2 and two different modern Samsung Smart TVs, laptop is modern i5-8259U 8GB RAM, and phone is Galaxy S20 all of them totally updated, so hardware, software and network are OK in terms of power and quality.
