I made a webpage with multiple galleries, some of them are hidden on load can will show when you press the "show more" button. It all works fine on macbook/desktop and android phones. But when we tried it on a Iphone the whole page starts lagging and the galleries are not displayed correctly. Already tried on multiple Iphone's and it is the same on each phone.
Here is the code I written:
For background information;
* I have 4 galleries (1, 2, 3 and 4)
Gallery 2 and 4 are hidden on pageload.
* I have a collapse text and collapse shape which both are hidden on pageload.
* I have a expand text and expand shape which both are displayed on pageload.
