Start up and auto- retrieve data from web

Thanks for your request.

You can set up notifications at Preferences menu so Store Manager will remind to synchronize data ,see screenshot --> https://www.screencast.com/t/n5mKDBYYhX1

Also, there is Direct connection type which is recommended to use in case you managing the same store from different computers to avoid duplicate errors same as the issue you've faced.
Direct connection synchronizes changes on the fly and does not require pressing Get and Post buttons.

You can find instructions how to set up Direct connection here https://www.mag-manager.com/useful-articles/quick-start-guide/direct-database-connection-settings/
or submit a ticket at https://support.emagicone.com/submit_ticket with your FTP details and store url so we could set up Direct connection for you.

Please do not submit any details here, since it is a public page and all data will be accessible to all our users.

Thanks for the reply, Bas.

Let's wait for votes to make this features implemented.

For now, you can use Direct connection type as its synchronize changes on te fly.
