At the moment I have 1200 products. But this has been the case even when I jusr uploaded my first 20 products last Dec. when i was testing out all the functions. In fact that took several hrs too. I thought it was just a server issue so tried different times. Lived with it for awhile. But I think this is really slow. 2 days of updating and by the time its done, changes might have been took place again on aliexpress. I can deal with slowness, but having to stay on the computer just to click Start when it halts is time consuming. Watching netflix and downloading is seamless so i believe connection is fantastic.
Wow! How many products do you have? Importimg products takes awhile too. It varies. Sometimes its fast. Some will get stuck on the spinning X on the button for several minutes b4 it turns to a check mark. But I am ok with that since you atleast leave it without the need to click on anything.
