We are having problems sending emails from BC when there is more than one address in the To or CC field. When trying to send it either fails or blanks out the field with more than one recipient.
We are currently experiencing this problem only in our production environment, which is on version 15.0.36560.0. In our sandbox (v. 15.2.39060.0) this seems to work fine.
Is this a known issue that will be fixed in an upcoming release?
