happy to hear that it works well on your side, besides the issues with plugins
regarding the Rotary Encoder II plugin available in the plugin store, it has a different implementation compared to the old one from @Saiyato , it makes use of dt-overlays available only on Raspberry Pi, so it won’t work on other platforms. You might give a try to the old one, but it might require some adaptations to work on Volumio3
regarding MPD_OLED, the developer applied some changes recently, that might cause issues on Volumio. I suggest to ask for help in the dedicated thread
