Not possible to remove stored signatures from Fill and sign yourself in Adobe Acrobat Pro

Hello,

I hope you're doing well, and we apologize for the delayed response and the trouble.

Please ensure you have the latest version of Acrobat installed on the machine: 24.005.2039x Planned update, Jan 23, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check.

Let us know how it goes.

Thanks,

Anand Sri.
