Hello!

As soon as I check in to PAM via Devolutions Workspace on my smartphone, I receive the following error message by email:

In general, it takes some time for accounts to be upgraded before the changes actually take effect, even if the browser is refreshed or restarted.

Hello,

Thank you for reporting this issue.

We will investigate and get back to you shortly.

Are you still using DVLS 2025.3.14? If not, we strongly recommend that you update to version 2025.3.16 for this security fix.

Best regards,

Hi!

I've updated to 2026.1.6.0 and using the devolutions workspace app 2026.1.0 build 101.
Looks like the issue is fixed at this version. Checkout over Devolutions Workspace app is working as expected.

Best Regards
