Hello,
1. Check to see if the cron jobs are running. In the admin dashboard, under the debug tab, you will find the information next to: “Cron jobs last ran on”. What do you see?
2. If you still can’t figure out why cron jobs are not running, please show me the details of your airdrop.
3. Finally. Does the airdrop run if you apply it to a more standard role, such as subscriber?
Let me know about these three points.
with regards
