I am using the new UI and didnt see a post specifically to outline issues/bugs.
I am noticing discrepancies between the live preview and iOS companion app displays.
The issue is that the margin and component spacing is the same on design screen as it is on live preview but not the same as on companion app. Here is an example of what I mean
specifically here you can see that in the companino app screen shot, the text overlays the image. in the live preview, the text is below the image as it should be.
