Request signature is not working URGENT

Hi @Monaco Media Enterprises 

Sorry to hear about the trouble caused.

Looking at the screenshot, you are using the Acrobat Pro desktop application to send the document form signature. A couple of questions to identify the root cause of the issue: 

1- Is this an issue while sharing any specific file for signature?

2- This is an Acrobat desktop app. Please try sending the file from acrobat web as well and see if you get the same issue: https://acrobat.adobe.com/link/tools/?group=group-sign 

Here's a similar discussion with a couple of suggestions, which has helped the other users. please try them and let us know if it makes any progress at your end https://community.adobe.com/t5/acrobat-discussions/quot-request-signatures-quot-locks-up-on-quot-uploading-to-adobe-sign-quot-screen-this-has-been-a/td-p/12570117/page/2#M409756
