There is a new way to add links. I’m not quite sure how to explain it concisely, so we’ll have a practice in here before I write it up… 
Basically, you copy your link to your clipboard, navigate to your composer and highlight some text you want to be the display text:
And then select ‘paste’ (or the link snippet from your clipboard if you have a swish one). That should automatically add the hyperlink in for you. 
Does that make sense?
