I use Ratio Pro on my Redmi 8 from 1 week now, but can’t find a way to use color mode function for apps. It says “Ratio doesn’t have the right permissions to use this feature” and in Permission settings it says “This permission can only be granted via BllocDock”.
In the developer options, in addition to activating USB debugging , installing via USB , try activating USB Debugging (security settings) and then reinstalling Ratio via Bllocdesk. It worked for me (Redmi Note 8 Pro)
Thank you, It worked now!
