[closed] New roads does appear in Standard View ?

Hi,

This is my first time taking part in open street map. Just now I have drawn a lot of road ( residential roads ) in Yangon area. After Editing, I saved it. But when i switch to View > Standard View, the roads that I have just drawn do not appear.

But when i recheck again in edit mode, my drawing are there. I don't understand what is happening. Is there time needed for the real map to refresh ? Thank you.
