Reloading of step after button click submission

I’m having this issue on my form’s final step that takes files for submission. The user should upload the files and then gets redirected to a final confirmation page.
What is happening is that after clicking the button it starts to load, then stops loading but it seems some processes are still taking place, and after several seconds only then does it move to the next page. I have a loader after the button click and tried both as a whole page and only button loader.
Here are videos to show this.

The issue is that this is confusing users a lot, which click multiple times the button after the original loading because it seems that the input was not received.
What is worse is that I use this as an event to measure form completions and because of this I am receiving multiple firings for the same forms which should not be the case.

Any idea if this can be fixed? Is it a delay happening at the form level or does it have to do to the setup of logic integrations I have?

Hope you can help out. Thanks!

Hi there, could you share what account and form this behavior can be observed on?

Hi Eri
This is the form: XZUYJP and Upfundingcapital.

I already solved the main issue with measuring form conversions by changing the event that triggers the conversion, instead of taking the FormCompleteEvent after clicking that last button I now trigger it with the last Thank you page load.

However, the issue with the button is still not very good UX, not sure if this can be improved in anyway.

Thanks
