Maintenance windows and paused sync
Knowledgebase
Planned maintenance is listed in Announcements. Catalog pull or marketplace push may wait during that window. After it ends, run the queue once—do not click the same batch repeatedly or you may double-publish. If it hits a peak sales period, name the channel (e.g. Trendyol stock) in the ticket. Your own store maintenance (OpenCart/Woo) also stops sync; check the shop cron.
