I'm using a DLNA server (Serviio), and Skybox on my Quest 2 has two problems:
It returns cached folder and file names *even when the DLNA server is disabled or even when the Quest 2 wifi is turned off entirely!
It refuses to refresh the file list. The Refresh button blinks quickly and always shows the same files. The only reliable way to actually get it to refresh the file list from the server is to do a Factory Reset (doing the Clear Cache has no impact).
It's been iffy about refreshing for months, but a more recent version (maybe within the past month or so?) really broke this.
I'm using v1.1.4.
