Payment Intent ID Not Valid

This issue has occurred for two transactions within the past week. It was found after reviewing session recordings for one customer and a complaint from another (verified through session recording). I have Forminator form on website via short code.

User fills out form and enters payment information. When they hit submit, the Payment ID Not Valid error message pops up.

I’ve tested with live payments and could not create the error. Also, other customers were able to successfully checkout. I checked the Stripe Developer logs and the payment intent was created but there were no errors recorded.

This issue was potentially caused by having an older version of Forminator Pro we tested briefly and then deactivated a few weeks ago. We completely removed the Forminator Pro plugin and installed the recently updated Forminator free version (we only use one-off payments which is included in the free version).

All evidence points to an issue within the Forminator plugin itself for these edge cases. Any information on how to prevent this in the future.
