Post Submit Lightbox Blank

Hi @laxgirlie

Thank you for flagging this issue. We’ve noted this for our Design and Engineering teams to review, and they’ll use this feedback when implementing fixes and improvements in future releases.

This seems to be something to occur when animations are enabled, so for the time being you might want to consider disabling those. Check out this Squarespace help article for more details:
