Hi, I have the same problem on Windows 10 with a 100/50Mbps internet connection. The first release I installed was not usable. The actual, 10.3.7, go faster, but not enough. For me, it's not possible that each change we do (type one or two words, change notebook selection, move notes to other notebooks,...) need seconds to wait for server connection and data transfer. The worst is that in those 1-2-3 seconds we need to wait, evernote is stucked. For a productivity tool, at the moment is sadly not productive at all.
