Hello,
after using 2.0 and 2.5 in my app, the getFolderListHierarchical() is very, very slow.
In version 1.4.0.0 e.g. the function works in 1 sec or faster. In V2.x the function needs until 20 sec!!!
I thought it is a Dropbox problem, but after reinstall version 1.4. and compiling your Cloudstorage demo, it works fast then before.
It seems there must be a failure in V2.x. Could you check and resolve it?
