Ensure your device is connected to a stable network, as connectivity drops can interrupt the login popup and cause it to close.
Open a different supported web browser (like Chrome, Edge, or Firefox) and navigate to cloud.acrobat.com to see if the sign-in window remains open.
Ensure you are using the correct Adobe ID and password when prompted, and clear your browser cache if the page fails to load properly.

Frequently Asked Questions
Why does my Acrobat sign-in window disappear so fast?
This usually happens due to a momentary network interruption, an outdated Adobe Reader version, or a conflict with your default web browser's pop-up blocker or cache settings.
How can I tell if a specific PDF is causing the login crash?
Try opening a different PDF file from your computer. If the sign-in window works normally with the new file, the original PDF may have corrupted permissions or specific security policies applied.
Do I need to sign in just to view a PDF?
While basic viewing in some lightweight PDF readers doesn't require a login, accessing premium tools, cloud storage, or specific protected documents in Adobe Acrobat often triggers a mandatory sign-in prompt.
