I use the module v1.2.2 for my site Magento 2.3.4. It worked fine before but stop sending email last night.
For testing, change the config Frequency cron to */5 * * * * (sending an email every 5 minutes).
However, the system notes that email was sent but there is no email coming - https://i.imgur.com/dYvo6dI.png..
Do you know how to fix this?
