Fix Adobe Sign-In Button Not Working When Sending PDF for Signature
Question details
The user is unable to log in to send a PDF document for signature because the sign-in or submit button fails to respond across multiple web browsers.

- Product
- Adobe Acrobat / Adobe Sign
- Device & OS
- not provided
- Scenario
- Attempting to authenticate an Adobe ID to send a PDF document to a recipient for an electronic signature.
- Observed behavior
- Clicking the Submit or Sign-In button produces no response, freezing the login process and preventing the PDF from being sent.
Verify that your internet connection is stable and ensure that your web browser is updated to the latest version before troubleshooting the unresponsive button.
Verify Adobe ID and E-Signature Subscription Account
Ensure you are using the correct email address that is actively linked to an EchoSign or Adobe e-signature subscription.
Often, a sign-in button may appear unresponsive if the system encounters a silent authentication error due to an incorrect account type. If your current Adobe ID does not have an active e-signature subscription associated with it, the authentication gateway might fail to process the request.
Verify that the email address you are entering is exactly the one you used to purchase or register your Adobe Sign or EchoSign subscription.
Search your email inbox for past billing receipts or subscription confirmations from Adobe to confirm the correct account email.
If you have multiple email addresses or a secondary work email, attempt to log in using those credentials to see if the button responds.

Perform Standard Browser Troubleshooting
Clear browser cache or disable extensions to resolve conflicts that prevent web page scripts and buttons from functioning.

Frequently Asked Questions
Why is my Adobe sign-in button completely unresponsive?
An unresponsive submit button typically happens due to browser cache corruption, conflicting extensions like ad-blockers preventing the login script from running, or attempting to log in with an Adobe ID that lacks an active e-signature subscription.
How do I know if my Adobe ID has an EchoSign subscription?
You can verify your subscription by logging into the primary Adobe account portal on a different device or browser. Navigate to the 'Plans and Products' section to check if Adobe Sign or EchoSign is listed under your active services.
Can I sign a PDF if my Adobe cloud login is failing?
Yes. If cloud-based services are failing, you can use local desktop software like WPS Office to open the PDF, apply an electronic signature offline, and email the document directly to the recipient.
