This works but now another problem arises: if I use the function "translate('somekey', {session.props.locale})", the "session.props.locale" property must be, for example, "en_US" while if I use the function "translate('somekey') the "session.props.locale" property must be "en-US" (this format, the other function, gives me an error saying: "Invalid locale format: en-US"). Depending on which one I use, I see the translations of certain texts working or not. Why is this? This is all quite funny
