I have:
- reset device to factory details
- checked multiple providers in M3U list (2 connections allowed) and XC (with 2 connections - enabled from the provider on my request). Was able to see PIP via XC. XC indeed check for connections allowed and won't show PIP if it is just 1 but M3U lists will show PIP regardless of the connections.
- replaced ethernet cable
- replaced HDMI cable
- switched to 5Ghz (from wired just to see)
- checked speedtest both via VPN (140Mbps) and without VPN (250mbps).
- tried with VPN on/off
Well, same issues. If 2x 50fps streams are running, I do hear audio properly but things with picture gets crazy or in very slow motion.
I came across this post , how to actually tell if someone bought a fake device or not if I get regular updates etc? I paid 2 years ago (Feb 2019) incredible price at launch in UAE of $80 (seller Caronic). Today the same seller still sell Z8 through their website and Amazon AE for $136.
