Hangouts tries to reply to short code numbers as MMS and fails every time.

You know those short code numbers that are six digits that automated systems use to send you notifications for appointment reminders and whatnot? For whatever reason, hangouts with fi has been trying to automatically respond to those as MMS, which always causes it to fail. To reply to these messages I have to manually create a new conversatation and send as SMS to the short code number. It then shows up as two different conversations under hangouts.

Why is it defaulting to MMS for short codes now?
