Klck not working at all

Issues

Hi. Not working on p20pro

You had "Screen Overlay" permission allowed for Klck in your phone?

You can search it in the settings of your phone in the information of Klck, Permissions, Advanced, allow Screen Overlay

Yes. "Display over other apps" is on. Still the default Huawei lockscreen appears.

Is there a way to enable it in the EMUI settings?
