Basic functionality works, but some websites become completely unreadable. Also, it doesn't really turn "off" correctly, and I have trouble getting it to ignore certain websites. For example, duckduckgo has a great built-in dark mode, which I always use. However, this app doesn't think I should use dark mode during the day and overrides my settings, even when ostensibly "off". Super annoying!!! No way to tell it to just ignore duckduckgo.
