Email Reports aren't sent

I created a Email Report with daily schedule, but I don’t get any mails. When I use ‘Send Report now’ everything works fine.
How can I fix this?

Hi,

Quite a few people have reported this exact issue and no one can repoduce it:

My current guess is still this:

One way to find out would be following Emails from Matomo are not being sent, how do I troubleshoot and solve the issue? FAQ - Analytics Platform - Matomo and sending an E-Mail via php-cli.
