If you want to apply the edits made on Shopify to other channels as well, all you need to do is switch ON the Edit from Nembol function in the settings of the channels you want to update accordingly.
This way, all the changes you make will be automatically implemented and synced across channels.
If you want to keep content independent, leave the “edit from Nembol” switch OFF.
Once you’ve set your channel(s), you’ll be able to update your listings into Shopify and consequently have your edits on Nembol and across the chosen channels.
