I am also experiencing this. It's caused by other notifications, especially persistent notifications like a weather notification in my case. Disabling other persistent notifications until the Enpass team fixed this problem is a good workaround. I disabled my persistent notification, since then it's working fine.
Hi @Sushubh
Sorry to hear about your trouble and we apologize for the inconvenience. Our dev team is already aware of this and they are working on it. The best workaround at the moment is to clear other notifications from the notification bar, then try to auto-fill via Enpass notification. Till then we request you to please bear with us.
Hi @Ovchinn1kov
Thanks for writing in.
I have noted down this issue and will try to fix asap.
I would like to let you know that this settings mention the color of the theme not the color of icon of Enpass in Taskbar of the system. So if the theme of Windows is dark you should choose Show System-tray icon for Dark theme and it will display light icon.
Cheers!
