Disable language setting/Set default language

Would love to have a way of being able to disable or set a hard default on the app language.

We are having issues where all of our apps are designed in English but we have users with different phone languages that confuses them by setting different action button/menu buttons in their language but everything else is in English.

Everything just looks more professional and fresh when we have the same language all through the app and for our visual instructions of the app that shows everything in English.

Feels like it should be a small setting in the settings panel for the app where this may be set?
