Frequently Asked Questions

Why does Adobe Acrobat keep asking me to sign in?

Continuous sign-in prompts usually occur due to corrupted local login tokens, outdated application software, or background firewall settings that block communication with Adobe's activation servers.

Can a VPN or proxy affect PDF sharing in Acrobat?

Yes. Strict proxy servers or Virtual Private Networks (VPNs) can interrupt the continuous web connection that Adobe requires for real-time document sharing and synchronization, leading to unexpected logouts.

How do I check my current version of Adobe Acrobat?

You can find your current version by opening Acrobat, clicking on the 'Help' menu, and selecting 'About Adobe Acrobat'. The version number will be displayed in the pop-up window.
