Just now emails popped into my account!
It seems the server where I host those emails has some latency 😀
OK, here a screenshot of what I received:
- clearly, it sends the email to the user that submits the first post
- clearly, there are 2 emails in the same account inbox
- clearly, the second user did not receive his email
I have replicated, finally, and have clear steps + a bug description.
This is now going to the Developers straight away.
Thank you for your immense patience and I hope we will have a solution ASAP.
