Crab sync has some important points to note during use:

1. Sub-stores can only sync inventory to the main store and cannot sync product and variant content.
2. When syncing product media files, only images and externally linked videos can be synced. Video files and 3D models cannot be synced for now (but will be soon).
3. When the main store uninstalls the APP, the synchronization log and the association between products in the sub-stores will be removed. However, products created and inventory quantities synced based on the automatic sync in sub-stores will be retained. Please be cautious when uninstalling the APP from the main store.
4. Negative inventory numbers cannot be synced.
5. If a sub-store establishes variant associations in manual mode and then switches to automatic mode, the associated variants in the sub-store will be updated synchronously when the main store's variant data is updated.
