Form submit button not showing up on mobile

My first time using and deploying on streamlit. I’ve managed to get the app up and it works as expected on a desktop but for some reason whenever I access it on a mobile device the submit button is not visible.

I can see the outline of where it should be but the box is blank. Have tried a couple of different things with the layout but nothing seems to work, it just doesn’t show up.

App is here:

If you go to it on mobile, click on the selection box in the top left to go to “Score prediction” there should be a submit button right above the image. Here is a picture of what I mean:

Does anyone know what could be causing this? Thank you!

Just after posting this I was able to narrow down the issue to the browser. I tried on the Chrome mobile browser and it works fine, but on Safari the button doesn’t show.

I figured out it was an automatic content blocker on my safari browser! Disabled it and it works. Feel dumb but relieved. Considered this one solved!
