You should consider the “structure” of the Lumïn app.
It has an internal database, quite unique among apps, icons from 1st to 6th work on the internal db while the 7th, folder view, works on queries to Minimserver.
This is because you can use the app with a Lumïn streamer with
- directly usb attached hdd (or a nas shared folder, and anyway without any upnp server) then icons 1-6 become indispensable
- with an upnp server like Minimserver, strongly recommended by Lumïn, then the 7th icon let you use all the Minimserver strength.
