How to turn off price synchronization? Manage prices directly on the channels

You can choose whether to manage prices from Smoobu for certain connected channels.

You can turn off price sync by going to your Pricing tab > Settings > Percentage adjustment

Untick the box to turn price sync off for a channels. This action will prevent Smoobu from pushing new price entries to this channels. 

Remember that this does not apply to Airbnb because Airbnb decided in August 2018 that it is mandatory to manage your prices through the PMS once you are connected to one. You may turn it off but Airbnb will not allow you to manage your prices from their Airbnb interface.
