Trying to export some graphics to Powerpoint as .SVG and everything looks great in Illustrator but things are off in Powerpoint. Specifically, it seems like the text object size might be changing? In the attached files you can see that text that used to fit inside of a rectangle doesn't fit anymore in Powerpoint.
I can't open the Powerpoint jpg so I not sure what is happening and I assume you are doing Insert>Picture>Picture from File? I can't replicate the problem, it is working for me. Have you tried it with another file to see if it works at all?
