I've done some mass updates on product attributes in the catalog view. The attributes updates sucessfully via cron but I still have the notifications in the admin. These have been there for about a week. I've tried a full redeploy etc but they still remain. How can I clear these? Where are these stored in the DB?
Using Magento 2.4.0
Task "Update attributes for 3 selected products": 1 item(s) have been scheduled for update.
You can check cron_schedule table in Database with status pending and can check what processes are in schedule.
Magento creates three log files, which are var/log/magento.cron.log, var/log/update.cron.log and var/log/setup.cron.log. You can watch these log files.
Hope it will help you to find which cron process is in queue.
