A major flaw for everybody using KeePassXC: after updating to v.1.9.1 all KeePass functionality is gone. Anyone who relies on the Cryptomator/Keepass combination should not perform an update until this is fixed - and confirmed as fixed. Ruined the day completly as almost everything here sits in different CM containers and having to type/p&c in the passwords each and everytime is a time consuming, frustrating pain in the arse, disrupting and making effective workflows impossible 
- Disable loading of plugins by default (#4136): Custom plugins are not loaded by default anymore. To allow loading of plugins, specify the plugin directory in the admin config.
(Release Notes 1.19.0)
Or, you can just set up Auto-Type for the Vaults in KeePass(XC). As the title of the password window is named after the vault, it can be recognized by KeePass.
