I did try to go the WebDAV way but, at least for me, after 30-45 min into a video, reccuringly the streaming drops (I get an error message). I can restart a movie and it picks up where it left it but still, not as good as with a local NAS (I went back to that) or, say, GDrive (I tried that successfully). I can’t tell if WebDAV doesn’t handle caching as well or what the problem is exactly. I opened another thread on the forum asking if people use WebDAV and pClud but got not reply.
Let me know how that works for you and thanks for the feedback.
