How can i change the language to english in MN 4?

I installed MN4 via the App Store, but everything is in CHINESE. Sorry, I cannot spell Chinese and I tried to find the language setting with a translation app, bit I cannot find the settings menu for that:
PLEASE SHOW HOW YOU CAN CHANGE THE LANGUAGE.

Thanks

I looked in both the App settings and in the iPad system settings. I do have an older iPad so it isn’t the latest iOS however I found no way to control the language of individual apps on the device. No setting within MarginNote allows you to change the UI language. This must be something with the region store you downloaded the app from?
