English as interface language please! Why cannot I get that. Very annoying. Hardly anybody uses Dutch on these forums. Please hurry. Is very annoying.
Also the level of translation is childish. Keyframe translate as Hoofdframe and so on. Even starters are not helped this way. When they have a question and search for an answer nobody understands "hoofdframe".
Are you asking about how to get the forum language to be changed or how to get the language inside an app to be changed? You've posted this in the Forum comments section which is regarding these forums themselves. If you are asking about an app, let us know which one and a moderator can move this thread to the appropriate, app-specific, support forum.
If you are asking for something like AE to be in English instead of Dutch, you uninstall it the app, change your language in the Creative Cloud app, and then reinstall the app.
If you see translation issues in an app, file a bug report.
