I have the same problem, but I have found that it is related to the web browser.
If I use IE, then I can only see the 30 or 45 folders/files in a share. it seems like the rest aren’t loading so that I can’t scroll down far enough to see them. If I’m very patient then they will sometimes keep loading and eventually appear after a few minutes (I mean MINUTES literally).
If I use Firefox they all load up immediately and I see the whole list from the beginning.
BTW, it is not related to internet speed since I have a very fast connection and I get all the files instantly with Firefox when using the same computer. Also it isn’t related to the specific computer since I’ve seen the behavior on three computers. I have also seen this behavior when the same computer is used in 3 different locations, so it’s not related to the geographic location nor to the ISP.
There is some problem with how mycloud is interacting with IE.
