Google tag manager/analytics tracking form submissions

Hi Guys,

I have integrated GA4 & google tag manager into my site to track analytics, but it does not seem to update once a form has been submitted & I am also unsure on how accurate the analytics are as its showing loads of new users each day but this is not the case.

Has anyone found a way to resolve the form submission issue on tag manager?

Thanks in advance

I was following this tutorial How to Track Form Submissions in Google Analytics 4 With Google Tag Manager (youtube.com) but the form submit was not shown by the tag (6:45)
