I started grouping all my visuals because it's so much nicer to work with, but I found a nasty bug I believe. When you group visuals together, when you create an email subscription for a report, it will put all those grouped visuals in in the top left corner of the image of the page. I dont think it should behave like that. I think it might have to do with the group having different x and y coordinates than the individual visuals, and that those coordinates now default to 1,1.
Hope you can help! For now I ungrouped all the visuals again and it looks good now.
