I've beat my head up, down, and all around this forum, Google, and through my own abilities, and cannot understand this issue.
My issue appears to be slightly different than anything I've come across. I have a simple side lightbox that contains my login/signup jumble, and it works perfectly on Desktop, however, in mobile, it will not appear. Even when I'm in mobile editor and in lightbox mode, it's faint. Almost acting as if 'hide' has been selected on it, which it has not.
Another tell-tale sign that it is indeed opening is that when I check it on the live mobile site, my quick action bar hides, indicating that the lightbox is indeed being prompted to open, it's just not visually there. I click anywhere on the screen and the quick action comes back, indicating the lightbox has been closed. I have seen deleted the quick action to see if it was having an affect on the lightbox functionality, but it was the same result.
Even when I set triggers to automatically open, no dice. As previously stated, it's faded out as if it's hiding, and solid once I click on it to edit. Everything is properly in the lightbox with nothing set to hide. I have created several other sites using this same design strategy for login's and can confirm that those are all functioning properly. Desktop continues to work properly throughout all these troubleshooting changes.
I have absolutely no trickery code that would first hide the lightbox then close it, it is just a simple, straight-forward onClick command that opens it.
