Hello @paulo_8095
I hope you are doing well, and I am sorry for the trouble you had.
From what you've described:
You're encountering PDF compatibility issues, especially when trying to digitally sign documents.
The platform seems to be prompting you to learn or troubleshoot, which you feel shouldn't be necessary for a paid service.
The free version made it easy to sign PDFs, but now the Pro version feels restrictive or broken.
Here are some common reasons why PDFs may appear “disabled” or “incompatible” for signing—and how to fix them without needing to learn anything new:
PDFs Created by Non-Standard Tools Some PDFs generated by third-party apps (e.g., scanners, converters) may not conform to ISO standards. Fix: Open the PDF in Acrobat Pro and go to Menu > Save As > Optimized PDF. Adobe Guide: Saving PDFs.
PDFs with Security Restrictions If the document has encryption or editing restrictions, signing may be blocked. Fix: Go to Menu > Properties > Security and check if signing is allowed. If not, you may need the document owner to remove restrictions. Adobe Guide: PDF properties and metadata.
Digital Signature Field Missing Acrobat expects a designated signature field. Fix: Use All Tools > Fill & Sign > Sign Yourself to add your signature manually. Adobe guide: Fill and sign PDF forms.
Please ensure that you have Acrobat Pro installed on the machine. We checked and verified your Adobe ID(email), which you have used to log in to the community, and see that you have an active subscription to Creative Cloud Pro apps, including Acrobat Pro. If you have the freeware Acrobat Reader installed, please use the Acrobat Cleaner tool to remove the app, restart the machine, and install Acrobat Pro. Sign in with the Adobe ID(email) to activate the susbcription and use the features.
Let us know how it goes.
Thanks,
Anand Sri.
