Cannot add images in the new version of Upfront

OMG the latest update to Upfront has really stuffed things around with what was a pretty smooth creative process! The changes to the on page UI are a real step backwards.

Cannot add any images whatsoever to anything. Drag the element onto the page and then the two nice big buttons to add new image or inspect gallery are completely missing. Now there is a tiny little + sign in the op LH corner.

Click on the + and the entire screen blurs out, as if it was going to open another window or something, and just hangs there. Cant do anything. Cant escape out of the action, have to close the entire tab and start again.

I'm just hoping that this is a dud / incomplete update because if it isn't then I don't think I will be able to use Upfront anymore, which will be a real shame.
