There are several ways of synchronizing prices manually to portals.

One of them is using SYNCHRONIZE tab in MANAGE / ONLINE PORTALS in specific portal's menu.

This can be used, when you need to synchronize prices and availability for a longer period of time, for example, because you corrected your room mapping or you have just connected to the new portal.
