I have noticed page of my website no longer display the full screen slider – until you touch the blank spot or navigate up or down.
The problem ONLY occurs on my iPhone. It cannot be replicated using Safari / Develop / Responsive Design Mode.
Chrome for Mac seems to display properly too.
I assumed it was something to do with Lazy Load, but switching on or off seems to make no difference.
PS. Not to worry. I have found turning off WP Rocket fixes the problem so will go back to them for help.
