Issue Description*

1. What were you doing when you encountered the problem?
Displaying Forms Using Elementor with plugin for Elementor from WpGive.

2. What were you expecting to see happen?
For the phone to shows correctly on desktop and on mobile devices.

3. What happened instead.
Form shows correctly on android phone but on some iPhones, the form shows blank, you can tell the form is there because you can type an amount but it doesn’t show anything.

What steps have you tried yourself to resolve the issue?
The plugin is updated to the last version. We tested it on several iPhones, on some it happens but on some it doesn’t. For example on my iPhone 7 it works great, but on another iPhone 8 plus we have in the office it does not work.

I’m also having lot’s of issues applying css styles to the form, the styles don’t seem to apply to it. We are currently using the Multistep form.

The issue of the Form no displaying is ONLY on mobile and on Iphones.
