sorry, i don't know how use these files, i'm an android user and i was able to install an old version of vlc on my amazon firetv using downloader and enabling unverified source file installation
i have the same problems with VLC on one of my two firetvs. in the one where 3.2.6 is installed appears the circle when i attempt to enter into my shared files on my windows 10 notebook. VLC 3.1.4 installed in the other firetv works normally instead. same problem on my samsung galasy s8 with VLC 3.2...
