Can I add the Mobile Responsive widget after form is published?

Dear Sirs,

I just realized that I forgot to add the 'Mobile Responsive' widget to my form and I have already published it.  
Can I still add the widget to my form?

If so, do I have to republish my form?  And will the link be different for my WordPress.org embed code?
Also, do I have to change the embed codes on all instances of my form on my website? 

And, will this affect any of submissions for my event that I've received up to this point?

Thank you for your help concerning this matter.  I look forward to your reply.

Hi CJ, please see my answers interspersed below.

1. Just realized that I forgot to add the 'Mobile Responsive' widget to my form and I have already published it. Can I still add the widget to my form?

- Yes you can. BUT, instead of using the widget, there's a better way to make your form mobile responsive. Just go to the FORM DESIGNER > click FORM LAYOUT > tick the "Make this form responsive" checkbox > then SAVE

2. If so, do I have to republish my form?  And will the link be different for my WordPress.org embed code? 

- No, you don't need to republish it, a page reload/refresh would suffice. Your form's ID/URL will never change even if you make changes to your form.

3. Also, do I have to change the embed codes on all instances of my form on my website? 

- No, you won't have to.

4. And, will this affect any of submissions for my event that I've received up to this point?

- Since you're only changing the look and feel of the form, it will never have any effect on your submissions.

Hope these answered your questions. In case you need further help, don't hesitate to ask.
