Hi zapptalesfabian,
As it’s hidden on mobile, we used browserstack (a cross platform emulator) to test and the predictive questions and this is the result:

But since browserstack is not exactly the same as using a mobile device (i.e. browserstack is a website..etc), would it be possible to ‘un-hide’ the search for mobile so we could test on a phone as well?
If enabling the mobile search isn’t possible, here’s two possible fixes you can try:
– Enable the mobile view search and try deactivating all the other plugins (in case there’s a plugin conflict that’s effecting the mobile load). If it works then, then reenable then one by one to see what’s causing it.
– If that didn’t work, you can try temporarily switching to another theme (like “Twenty Nineteen”)

A few additional questions:
1) What is the shortcode you’re using on the page?
2) Is the shortcode on a plain WordPress page or in a page builder?
