Hi!
This is the current Pro version:
This is the same thing in Beta 2:
Content has Scroll effects, but that is not seen anymore.
In addition, the name of the Row is lost, which is not a big deal, it is probably intentional to save space.
This can be tested with the native List element that has scroll effects on items: when opening Cornerstone and scrolling down to the section that contains this element, Scroll effects are extremely late compared to the current Pro version.
Edit: I just realized that images are taking much longer to appear in the builder than before as well.
Thanks!
