Hello, I utilized the code for a Frozen Header that I found in a video on YouTube posted by Wix.com entitled " Wix Code / How to create a frozen header that changes as visitors scroll", url - https://www.youtube.com/watch?v=8iO0G_qWqRY&t=15s . I followed the instructions to a tee and it worked fine in the "preview" and "publish" mode for about a week ( I did not utilize the transparent strip as I do not want anything visible upon load ). Now, for what ever reason when in the "preview" mode when you scroll down the "opaqueheader" (name of the strip I want to appear on viewport_leave) appears as expected. Upon viewport_enter the "opaqueheader" remains visible now ( does not "hide") and in "publish" mode it does not appear on viewprt_leave at all.
Any help resolving this issue would be GREATLY appreciated.
