MLS Import Plugin has a separate section to track the auto-synchronization process logs for the past 3 days.
The auto-synchronization process is automatic and hourly and keeps your properties up-to-date at all times.
The data stored in the logs is useful to the MLS Support team when tracking the import activity, a service you get by default when buying MLS Import.
For that reason, this settings area will not require any action from your behalf to use the plugin. However, it can prove useful to check if you want to know what are the new or updated properties.
