Soundiiz deals with dozens of thousands of sync executions per day and multiple syncs per user.
While Soundiiz can do this by using APIs (technical access to music services), we are limited by API quotas/number of requests per second/number of requests per user.
Soundiiz automatically sets the hour depending on our server's load / API load. That's why it's technically not possible/not allowed to set yourself an hour for a sync execution. But you can still see the expected execution time on your Sync details.
However, you are free to select the frequency of your sync execution (daily, weekly, monthly). Of course, we recommend setting the right frequency, depending on your needs! No need to set a "daily" frequency on a playlist that is updated once a month...
Thank you for your understanding!
