Since 13:47 UTC, each Enhance, cPanel/WHM and Plesk connection has a Sync section on its page. Every 10 minutes stays the default. You can also pick every hour, every 6 hours, every 12 hours or once a day.
For Enhance, this is how often we read your panel. A cPanel or Plesk script still reports every ten minutes, because it only reads a list, and we apply its latest report at the pace you chose. Nothing needs reinstalling.
A slower pace means fewer changes, but a new site waits longer for its monitor, and a suspended or deleted site keeps being checked, and can alert, until the next sync. Sync now always applies at once.
Thanks to Press Wizards for asking.
