Blank space on top of pop-up on mobile version (android)

Hi, how are you?
First of all, thanks for developing this plugin!
I’m really enjoying it so far.

But, in order to use Pop-up Maker in this project, I need to solve a problem I’m having when scrolling the pop-up on mobile.

When accessing the pop-up on my Android phone (xiaomi) I’m seeing something weird after I scroll down. There’s a huge white scrollable gap on top of the pop-up. I could replicate it on Chrome and the native browser.

I recorded a vídeo of the problem so it’s clear what is going on.

I’ve tried to replicate the problem on Chorme and Safari using an iPhone and I couldn’t. It worked just fine

Is there anyone experiencing the same thing?
Could anybody help me solve this issue?

Oh, by the way…

I removed every plugin and left only Pop-up maker, also, I removed every cache from the server side, just in case.

WP is fully updated and is running the latest version of the Divi Theme.
