Document doesn't use legible font sizes
48.64% legible text

Tap targets are not sized appropriately
97% appropriately sized tap targets
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more.

This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS.

Learn more.
