We have updated the email editor to a newer version. You will have all of the same functionality, but the toolbar above your email body will look a little different. If you can’t type in the body of your email, you will need to refresh your browser (while on the email page). Look for the little icon that looks like a curved arrow (see below) at the left or right of your address bar, depending on which browser you’re using.
When you click that button, the browser might pop up a message about “resending information”. Go ahead and click Yes, Resend, or Retry, and that will allow it to refresh/update.
As usual, if you notice anything that doesn’t work, please let us know.
