Every time I copy paste from Google Drive/Docs… it bolds the text and I’m unable to un-bold it.

When you copy and paste directly from a Google Doc (or another platform) into an Airstory document associated styling tags remain in the code and result in bolded text in the recipient Airstory document.

To remove styling or formatting when you copy and paste snippets of text from a G.Doc follow any of these suggestions: 

• Copy the usual way (Cmd+C or Ctrl+C) but to paste the text use Shift+Cmd+V (Mac) (or Ctrl+Shift+V on a PC) to ensure the pasted text matches the style of the recipient Airstory document.
