doesn't matter if you hard code it either. using gmail or outlook the subject line is replaced with the first line of the message.

This is an issue with the email apps, not on the share plugin.

You can research online (e.g. StackOverflow) about issues with Gmail or Outlook and the share UIActivityViewController.

We implement both the solution that uses UIActivityItemSource and the one that uses setValue(subject, forKey: "Subject"), if the apps aren't implementing the protocol correctly on their side, there is nothing we can do about it.
