I have a localized description of an app. I'm trying to add it in App Store Connect. Every time I save a red exclamation point is displayed with no explanation.
Then all my edits disappear on reload.
So I try to add a different screenshot in the new language before saving. But that fails with a red exclamation point as well but this time with an explanation: "Please save new locales before uploading screenshots or previews."
Well I can't because of the first failure. In the web inspector I can see the following error:
"status" : "400", "code" : "PARAMETER_ERROR.REQUIRED", "detail" : "The parameter 'filter[appStoreVersion]' is required but was not provided",
