I have kind of figured it out - but not fully
I can force the folder open on mobile on each page with a piece of code. This however only works on some of the pages? On all my german pages it works fine, but on all english pages only 3 out of 4 pages still show up on mobile with the same piece of code applied to those pages.
This is the code I'm using
<style>
[data-folder="/Services"] div {
display: block !important;
}
</style>
