With the new update for buttons, we have two issues with formatting. Both of these are with the rectangle shape, but may apply on others.
1) For text, if there's any word wrapping then the left or right alignment is ignored and it is only centered. Prior to the latest button release this wasn't an issue. After the Sept Desktop release, this is the same behavior in both desktop and the service.
2) Round Edges doesn't seem to apply any longer. See screenshot with 9px rounding that shows correctly within the desktop app, but not in the service.
