Issue with sending a contract for signing

Your message is clear and concise, but I've made a few adjustments for clarity and grammar:

Good evening,

I have an Adobe Acrobat Pro subscription, and I'm experiencing an issue with the electronic signature functionality. Specifically, I'm unable to find the feature to send a contract for signing. Although it appears on the interface, attempting to use it leads to a 403 Forbidden page. Normally, I have the capability to sign documents myself and send them to other signatories. Please assist me with this matter urgently.

Thank you.
