That’s in my case the same.. when I’m configure the cronjobs on a special cronjob site then they work. I figured out that maybe my hosting plan not supported cronjobs every minute. So I can’t get this plug-in work.
Have to move to another server but I’m not planned to do that. So I bought the plug-in for nothing 🤷♂️.
Unfortunately I have the same experience. All settings are good, only I can’t get the cron jobs working 🤷♂️. So the plug-in doesn’t work. I wanted my money back but that was not accepted ☹️
