Hello,
Thank you for the detailed follow-up and for running the control test with the duplicated entry.
Regarding your questions, we currently have no known regression matching this behavior. I tested this on my side with the same extension version, using a website entry with a linked credential, including one stored in another vault, and autofill worked correctly. This may indicate that the behavior is related to the existing entries or the extension's local data in your environment rather than to linked credentials in general.
To narrow this down, could you please run the following tests?
Create a new website entry for the same login page, linked to a new test credential entry with dummy values, and check whether the extension fills it.
On one existing affected entry, make a small change in Remote Desktop Manager (for example, add a character to the description), save it, then click Refresh in the extension and try the fill again.
In the extension, use Copy password on an affected entry and confirm whether the correct password is copied.
If the issue persists, please collect the extension logs by following the Edge section of this article: https://docs.devolutions.net/password-manager/knowledge-base/browser-extension-knowledge-base/devolutions-password-manager-browser-extension-troubleshooting-connection-logs/#edge Under Inspect views , the link may be shown as service worker or background/background.html depending on the extension version. Once the DevTools window is open, try the fill on an affected entry again, then send me a screenshot of the Console tab and of any request shown in red in the Network tab.
These results will help me determine whether the issue comes from the existing entries themselves or from the extension.
I look forward to your reply.
Best regards,
