Hello
I have a Huawei P30 PRo and I am facing to the same issue as described by @XDptguOE. I followed his explanation about installing the plugin and so on. Now I have a Keepass2Android notification for “androidapp://com.brave.browser” entry. I can fill username/password manually by selecting another entry but it should be a temporary solution.
@Mattches did you have time to look into this issue ?
