Amazon FireTV 4K - NAS hard disks "disappear" after accessing one NAS, changing to a different NAS, then trying to go back
-Fire OS 6.2.8.1 -FireTV Home Version 6321001.1
-FireTV Device with VLC installed: FireTV 4K "puck" version (not the stick and not the cube)
-FireTV 4K's Network Connection - Wi-Fi with speed measured at 250 Mbps with Wi-Fi speed app (wireless AX3200)
-Connected to pre-amp/processor via HDMI
-Noticed this happening with 10-bit UHD/HDR 2160p content, but have not confirmed whether it happens with 1080p content
-Using VLC to access Local Network NAS drives for music and movies
-Using DLNA access to NAS drives to access the "Browse Folders" option and navigating subdirectories to get to the content I want to watch.
When I view movies or TV content on NAS1 then stop and change to other content on NAS2 then stop and decide to go back to NAS1, VLC Media Player reports "No media files found" even though it had already played media files from that NAS once. I have to access Settings - Advanced - Quit&Restart then return to the NAS directory to get the filenames list to reappear. The "Refresh" button in VLC does NOTHING for this problem.
