Goal works on some mobile phones but not others

Hello.

I am having issues with a goal and hope somebody can help me.

My goal is set up so after an individual fills out a brief contact form they are redirected to a special page.

For some mobile users, the goal works as its supposed to. For other users, the contact form never appears. They are essentially bypassing it and going directly to the special page.

I cannot figure out why the goal (the brief contact form) is working just fine for some mobile users and why others can completely bypass the goal? From the tests I have done, it seems like iPhone 12 users are the ones that have been able to bypass the goal.

There are no issues with the goal working properly on a regular computer. This is a mobile issue only.

If it helps to know, I am using Contact Form 7 as the goal’s contact form.
