UPNP not visible on Amazon Fire TV (but visible on Amazon Fire TV 4K)

Hi,

I own an Amazon fire TV stick and a fire TV 4K and both are running the latest available version of VLC for Fire. Both are connected to the same Wifi network. I have a NAS that has UPNP and SMB sharings.

I noticed that, on the Fire TV 4K, I can access both UPNP and SMB sharing but on the regulare Fire TV only the SMB sharing appears (not the UPNP).

I have tried to uninstall/reinstall VLC on the Kindle fire to no avail, UPNP share remains invisible.

Can you confirm wether it's indeed a bug ? Thank you Could you please confirm wether it's a bug
