I'm glad the technical team is looking into it. Here's another data point:
Mac OS 14.5
Brave Version 1.70.123 and
Vivaldi Version 6.9.3447.55
Enpass Password Manager 6.11.0
Enpass 6.11.4 (1803)
My workaround: Go to the Extensions page in the browser. Disable then re-enable the Enpass extension. Go back to the page you're trying to sign into and refresh it.
This happens very sporadically, in seemingly random web sites, and has been happening for several weeks.
No issues in Firefox.
Looking forward to a fix... thanks!
