Survey Formatting Issue on mobile phones

I have had several people say they couldn’t complete my survey because the drop down arrow for my rating questions is not showing.

It seems to only happen on some phones, it works fine on mine which is a google pixel, using the chrome browser.

So it appears that these errors are only happening on iPhones.
The error message only shows on iphones but once you click okay the survey runs normally and still uploads responses.

The video shows how the drop down menu won’t come up for the last two questions.
