Im having trouble uploading maps from my computer to the roll20 blank maps in game, the file size is on 668KB and the file isnt uploading. I get as far as the loading bar with a very small bit of progress but it doesnt move from there and i have left it for hours before (left it up and went out) my internet speed is quite good as well being able to download things at a average speed of 5.6MB/S. Any help would be greatly appreciated.
