love your box titles. It is crashing my iPhone when I launch from exact error page or if I go to the home page without the /Test and then select a test from the menu. Here is what I get on my iPhone 11 Promax 512gig running ios14.
if I open a desktop browser but reduced No Problem, it opens fine.
This is running under a blankstrap theme. I had the same problem in source.
I separated it out to a subpage so it is easier to isolate. /test
so open anything on desktop no worries
On mobile whichever path you choose is going to crash.
