Fill and sign not available please help

I'm currently unable to fill out my documents in PDF as I had done so before. I've check through the document settings and it only shows page layouts. Such as continuous pages, single pages etc.

Hi there,
I hope you're doing well! Thank you for reaching out.
It looks like the document has restrictions that prevent you from using the Fill & Sign feature. If you received this file from someone else, please ask them to check the document settings and remove any password protection or restrictions for Fill & Sign. Once they do that, they can share the updated file with you.
