Did you try to install the plugin with the cordova CLI? `cordova plugin add cordova-plugin-theme-detection`

Please try to reinstall the plugin or readd your platform. I'm not able to reproduce this issue

It shouldn't be a problem with MIUI, I'm testing on a Xiaomi device, too. Are you guys using any plugin for app development?

How did you install the plugin? Are you using any framework? I've tried to reproduce the error, but for me it works fine on iOS 14.3
