Update Adobe Acrobat and Refresh Your Session
Resolves authentication glitches and software bugs by updating the software to the latest release and forcing a clean sign-in session.
Acrobat relies heavily on background authentication services for premium features. Outdated software or a corrupted login token can cause the blue sign-in screen to hang.
Open Adobe Acrobat, click on your Profile icon in the top right corner or go to the Help menu, and select 'Sign Out'.
Navigate to Help > Check for Updates. Follow the on-screen prompts to download and install the latest available Acrobat DC release.
Restart the application, click 'Sign In', and enter your correct Adobe account credentials to refresh the authentication workflow.

Test the Document and Verify Adobe Sign Requirements
Helps isolate whether the freeze is caused by a specific computer, a corrupted document, or an Adobe Sign service outage.
Use WPS Office to Fill and Sign PDFs Instantly

Frequently Asked Questions
Why does Adobe Acrobat freeze when I click Fill and Sign?
This usually happens due to a corrupted sign-in session or outdated software struggling to connect to Adobe's authentication servers. Signing out and updating the software often resolves the hanging screen.
Can I use Fill and Sign offline in Adobe Acrobat?
Adobe Acrobat often requires an active sign-in session to verify your subscription, which is why it attempts to load the blue Sign In screen. Without a stable internet connection, this screen may freeze if your locally cached credentials have expired.
How do I bypass the Adobe Sign-In screen for PDFs?
If you cannot bypass it in Acrobat due to a software bug, you can use alternative software like WPS Office to open the PDF. This allows you to use local Fill & Sign features without encountering Adobe's specific account authentication barriers.
