When using Windows.Storage.KnownFolders.MediaServerDevices, and folders derived from it, when there are more than 200 items in the folder, GetItemAsync() returns the first 200 items only, and there is no way to get the next ones. Even with GetFilesAsync(CommonFileQuery.DefaultQuery,201,220) which returns 0 even though there are files(and they are visible through windows explorer(so windows is seeing them).
Is there a way to access more than 200 files from folder?

2020-09-11T16:19:01.797+00:00 Yeah, i tried 3 different dlna servers including the integrated windows one, and with every one of them only the first 200 items get returned, while through windows explorer or my TV dlna client every item in the folder is visible. Then i found a bug reports for the same problem from 2018, so maybe no one use this feature(or is too low priority to be fixed), and is better to do the upnp listing manually

2020-09-16T01:51:39.007+00:00 Hi, we have noticed this issue and reported it, currently could you please avoid placing more than 200 folders or files in a single directory? Can you use sub folders containing no more than 200 items each? It's better to have fewer than 200 folders in a single level.

2020-09-23T01:40:09.737+00:00 Hi, could you please tell us are you seeing issues intermittently? What if you try again several times? Do the issues reproduce in 19041? If you still have that environment handy, can you update it to 19041 and try again? How often is this happening (If not always, what’s the frequency of occurrence?) Has it ever worked?
