All your languages are uploaded only when the uploadStrings is run for the first time.
As it's typical to upload only the base language for subsequent uploads, we have this behavior as a default choice. You can, however, enable uploading all of them.
In your Gradle file, add:
localazy {
// ...
upload {
showUploadAll true
}
}And then refresh your project.
The default choice uploadStrings will be changed to uploadBaseStrings and uploadAllStrings, and so you can decide whether you need to upload all (recommended only if there is a reason for it) or upload just the base language.
