Retrieving Picklist Translations in Lightning Component in Communities

Question

We have a lightning component that displays State & Country Picklists. The component is on a Community builder page with a French language community.

Note: The default language for the organization is English.

The lightning components calls into an Apex controller that executes the following

System.debug(UserInfo.getLanguage());
Schema.SObjectType objType = Schema.getGlobalDescribe().get('Contact');
Schema.DescribeSObjectResult describeResult = objType.getDescribe();
Schema.DescribeFieldResult contrfieldApiNameInfo = describeResult.fields.getMap().get('MailingCountry').getDescribe();

List<Schema.PicklistEntry> controllingValues = contrfieldApiNameInfo.getPicklistValues();
system.debug(controllingValues);

When this code is executed by a french user within a unit test (using runAs) or as anonymous apex (by a french user) the picklist labels returned are French.

However, when executed by the lightning component within the French language community by a French user (confirmed through the UserInfo call), we get only the English labels.

Any thoughts on avenues to explore would be appreciated.

Thanks,

As helped by Salesforce support, the issue appears to have been due to the use of a locale specific language variant.

The site is Canadian, and French. As such we chose to add fr(CA) as the language available. This language does not provide the translations as specified in the Translation workbench.

Instead, adding French (fr) as the available language DOES allow the translations to be sucessfully retrieved.
