Finally I found out how it now works - through notification area. But using built-in browser as it was implemented before with fully automated autologin was much more convenient.
Autofilling in Android does not work (Android 7, Xiaomi Redmi Note 4). Chrome browser is used by default.
System settings: Accessibility - Services - Enpass autofilling option is enabled. Autofilling option in Enpass settings is enabled as well.
What's wrong?
