It is unusable pretty much. I’ve now tried on two separate computers with the same results, regardless if trying to open an existing print job or uploading a new one. I have always used Chrome and even on the first try with 2nd computer its behaving the same way. right in the middle of a double sided job too so means I will probably have to scrap the whole first job 
Any ideas?
If you want to zip one or more of the SVG files you are having trouble with and upload it here, someone can take a look at it and offer any suggestions they might see. It’s pretty hard to just guess what’s causing the problem without seeing the file.
Oh no! I’m sorry to hear you’re running into lag on multiple computers.
I see you already emailed us about this and we’re working on it there, so I’m going to close this topic.
