Primary Language Change issue

Double check your screenshot inventory, review specs. Something is missing, and/or incompatible.

I have the same issue. No clue till now

Same issue over here. All the screenshots are provided but it still says that they're not.

I got the same issue.

I have a primary language DE with all screenshot submitted and other language FR where I also have specific screenshot.

I did create a new language EN and added all needed screenshots (and double checked all other required fieds like what's new, etc).

I can switch my primary language from DE to FR but not to newly create EN.

From my point of view, what is needed is that all screenshot are submitted "for each version in this language" that means that even the published version also need to have the screenshot in that language (and is not using the one from the current Primary language).

That means that, for some of us, it will need two update to change the language. A first one to add screenshot on the published version, and another one to switch primary language because you can't change default language on a published version.

I think that is because, even if you can only change the primary language when preparing a new version, "The Primary Language will be immediately made available on App Store" as it is said on info (?) juste above the field.

Re-adding screenshots with selected language you want to be primary works for me.

It is a little bit tricky/complicated. You have to do two production releases. Firstly add screens for origin primary language (as usually) and also for new secondary language - release must be reviewed and approved by Apple. Then you have to do second release in which you can change primary language. So process takes several days to change primary language :(

First you need to remove all screenshots and hit save then go to app information and change language you want hit save again now back to screenshot you will your screenshots again and save done. :)

From the doc,

https://developer.apple.com/help/app-store-connect/manage-app-information/localize-app-information

" Change the primary language You can change the primary language for an app. For a language to be selectable as the primary language:

You must have already added the language to a previous version.

App Review must approve the new language. If the language hasn’t been approved, submit a version with this localized metadata for approval. Then, select it as your primary language in a subsequent update.

You must have already uploaded screenshots in the language for all supported platforms that App Review already approved. If the screenshots for that localization are derived from another localization's screenshots, you must first manually add screenshots for that language and submit a version with these screenshots for approval. Then, change the primary language on a subsequent update. Learn more about adding screenshots and previews.

Note: If your app has a custom product page configured, you must also have uploaded screenshots in the language for each custom product page.

In Apps, select the app you want to view.

In the sidebar, click App Information.

In the Primary Language pop-up menu, choose the new primary language.

What does it mean "All supported platform"?

The previous released version has provided extra screenshots in the new added language in iPhone and iPad.

If I create a new version and try to adopt the new added language as primary language, should I then supplement the displaying Apple Watch and iMessage APP screenshots as well?

Or should the previous release version have already included the Apple Watch and iMessge APP screenshots so that the next version could be suitable to change the primary language?
