For those that may be having trouble using large svg files, e.g. iOS browser crashes, it appears that despite the fact that this was believed to have been fixed in the 2014.1 update, Edge Animate may still be importing the files at 10x their original dimensions and then scaling them to 10% so that they appear normal. A 500px wide image for example would be imported at 5000px which is too large for iOS devices to cope with - it may load OK, but changing the orientation or pinch-zooming could cause the browser, or even the whole OS, to reboot.
There is a simple solution fortunately: change the scale to 100% and change the dimensions to the correct pixel size.
I've lost almost 9 months to understand which part of my website was crashing IOS devices when navigating in landscape mode.
I would have loved to find this post when I noticed the problem.
I think Adobe should release a new update for Edge Animate to fix this issue.
