Jumping to a specific section in the cache listing does not work in the iPhone app.

[+Contramine]

I am the owner of a cache with a bilingual cache listing.
https://coord.info/GC9ZAYJ
The first part of the listing is in Dutch.
The second part of the listing is in English.
I created a link at the top of the listing to quickly jump to the English text.
And also a link at the top of the English text to quickly jump to the Dutch text.
The two links work well on the geocache web page.
The two links also work well in the app for Android phones.
But the links do not work in the app for the iPhone and iPad.
What could be the problem with the iPhone and iPad app?
