I found this article in a Facebook group on how to trigger the wp-cron externally when using Cloudflare could be helpful on your MainWP Dashboards.
This one is amazing! I will never know that Cloudflare is offering CRON jobs under Workers. Thanks at lot for this share @dennis. If you have more on Cloudflare free services, I am all ears.
