How long does a Collection update from the Tagalys dashboard take to reflect in the store front-end?

Any Collection update made from the Tagalys dashboard will be sent to your platform in minutes for individual collections. Based on your platform's configuration, theme, and cache preferences, when the number of collections updated is more in number, the updates are sent as queues and are processed one after the other by Shopify. The product position update is live on your front-end based on the caching preferences and timings of your front-end theme.
