Question

Catalog Resync stuck

Shopify catalog resync appears stuck for 15+ hours

My Shopify integration is enabled, and all products are synchronized into Klaviyo's catalog.

However, three recently published products are missing from their Klaviyo collection category even though they are correctly assigned in Shopify.

I initiated a refresh of Collection: New Arrivals yesterday afternoon. It has displayed "Updating category..." ever since.

Attempts to refresh other catalog data now produce the message:

"A catalog resync is currently in progress. Only one catalog resync can be run at a time."

Resyncing an individual product also produces a red error notification.

Is there a way to check, cancel, or reset a catalog resync that's stuck in progress? I'm using the Shopify integration and do not have access to paid support.

The affected category is Collection: New Arrivals, and the missing products are:

  • How I Show Love Tee

  • Don't Make Plans Tee

  • Don't Need a Hobby Tee

Hey ​@SnarkySpatula 

I don’t think you can cancel a stuck catalog resync from your side. The Help Center doesn’t mention a way to, and 15+ hours isn’t normal. A resync just pulls your latest Shopify products into Klaviyo right away. Klaviyo also updates each collection on its own a few times a day (collections show up in Klaviyo as categories) (catalog resyncs for Shopify).

Check New Arrivals again in case the tees have come over by now. If not, switch each tee in Shopify to draft (hidden) and back to active, saving each time. That has pushed a fresh update to Klaviyo for others, but I’m not sure it works while the resync is stuck. I will also tag @GabbyEsposito @Temi O. here so that they can escalate this to the correct people on Klaviyo’s side.

I hope this helps and thank you for sharing your question here in the community.
Cheers
