Please enable following in Email bodies so that developers can verify the true content they've configured.

1. Any hyperlink in Email bodies is shows as:
reflink="nw-stringbuilder-token-661c62d8-cd92-4f10-9273-e643486faf71" reftext="nw-stringbuilder-token-8596239b-6d13-445a-8bf0-7f58bfe9571b"

Nintex on-prem:
reflink="{Common:WebUrl}/IMPD Process Documents/Forms/Approved Documents.aspx" reftext="here"

Please enable actually inserted hyperlink. Otherwise, they only to find hyperlinks is via running workflow, which is not always possible.

2. When developer clicks on any content within email body and later clicks on View HTML, the cursor should point to corresponding position in within HTML. While it works in Nintex on-prem, in Nintex Online it points to the end of the email body.
