Automatically passing data to another form isn't working properly

This function does not work when using the JotForm mobile app to fill out. Please can you confirm if you can implement it with this system? It works seamlessly using a web browser.

Hello White Deer Wiils,

Thanks for reaching out to Jotform Support. I’m sorry you're having difficulties getting that feature to work. May I know the Form URLs of the forms with regard to your concern? If you could also specify which is the Source form and the Target form, then that would also help us identify the problem.

Once we hear back from you, we'll be able to help you with this.
