@scullchr I took a look at your Klaviyo account and was seeing that errors were pertaining to catalogProductAttributeInfo soap call not existing so I added a flag to your integration to not make this call and have re-enabled the syncs to run again.  Let me know if issues persist.

Hi @klaviyojad 

Thanks for taking a look.
If I didn’t mention this is for the Production account.

Unfortunately, I still get the same error about 5 minutes after re-entering the credentials. (see attached).

Hi @scullchr I could see that the account for which I added the flag for before, you changed the integration settings.  You see the special flag that we add gets reset when you remove the integration and you need to work with Klaviyo Support in order to have it added again for you.  I have gone ahead and re-added it and requeued the sync. 

Otherwise please work with email support for questions like these as we do not want public information revealed here as this is a public forum.

Thanks.
I removed it because it was not synced.

Currently since you have reset it again, it still looks the same and is not syncing. 
Can you provide in an email to me what you have changed via admin or what I need to do in order to reconnect.

Should the catalogue automatically be pulled in also as I am yet to see product?

Can I email you directly?
