If your client can't see their digest, it's most likely one of these two reasons.
A browser issue
Ask your client to:
Switch to Google Chrome
If they're already using Chrome, try opening the digest in an incognito window
If it still won't load, clear their cache and cookies
A VPN
Your client may be opening the email through a VPN or remote desktop (like Citrix). Ask them to open the email directly on their own computer instead.
