Hello Relf,
Welcome to the MikroWizard Team,
Seems you figured it out with cron , as you already mentioned cron needs examples and of course, needs to show an Error message with the wrong cron to the user 🙂
here is a website with examples of cron that you can use before we add some in the Front app
https://crontab.guru/examples.html
About the permissions please make sure you are clicking on the plus icon in front of the list! as following image:
First of all please select the device group and permission on the list
1. click on the plus icon
2. you should see it added to the list
3. click save to save permissions added
About the website is reported to team and the profile link will be added today
