digest, emails not sent
I am starting a new community with NodeBB
I have configured Weekly digest by default.
I have also configured the email plugin, so that it is sent via smtp.
Email is working just fine, from settings test, and for invitation workflows.
However, I noticed that the digest emails were not sent.
I can see in the logs the following message:
30/4 12:00:00  - info: [user/jobs] Digest (week) scheduling completed. 17 email(s) sent.
however, there is no trace of the emails, not even an attempt to connect to the smtp server.
I did straight after a test with settings/email and email is working.
What could be going on here?
Is the digest functionality compatible with all email plugins? could that be problem?
