Help with a locked document

Hi @olwami29200318xo0n,

Hope you are doing well. Per the description, you want to sign a document that is locked.

If the document is sent to you through AdobeSign, you can sign the file using Acrobat Sign mobile app or the Acrobat Reader Mobile App. If not, you must use the online portal (https://acrobat.adobe.com/link/home/) or the desktop version of the application due to limitations on mobile.

Hope this clarifies your question.
