Unsaved Form Block submission issue fixed - can I add these subscribers manually or..?

Hello! I had two Form Submission Error emails this AM stating that my form block submissions to mail chimp had failed. I followed the help guide and think it's fixed, but now what do I do with these two potential subscribers? They weren't added to my subscriber list - do I just manually add them??

Yes, at this point just manually add them on your website page. Or check Mailchimp and see if they were added when you attempted to fix it. You could always add them in Mailchimp too. 

Would you mind telling me how you went about fixing your issue? I tried to fix that same issue we've been having but I got another notification this morning that another form submission error occurred.
