We built our app in 8 languages, and following the procedure described i this post:
When it was published on app store we discovered that in the information section ->languages only English is listed.
Do you know where apple takes the list of the languages for the app? Because there isn’t an option in appstoreconnect.
Thanks in advance.
I solved this by adding
<edit-config file="*-Info.plist" mode="merge" target="CFBundleLocalizations">
<array>
<string>en</string>
<string>de</string>
</array>
</edit-config>
to config.xml 
Thanks a lot!
I’ll let you know if this will works.
