Prestashop sync not working

I am a new system admin working on restoring a dormant website. We have access to the old Klaviyo account, and I am getting it connected back up.

We are using Prestashop 8.2 on PHP 8.1. 

I have the Klaviyo module set up, and a current version of the PS newsletter subscription module (v2.8.3 - b). I cannot get any sync to work - either for user accounts or newsletter subscribes.

It can retrieve a list of lists from Klaviyo (so the api key works) and for testing purposes I am using “Newsletter”, which is pretty empty.

On the Klavyo side I installed “Prestashop” from the app marketplace andput the websiervice ID in. It can retrieve my store name so that seems right as well.
 
Not on multi-store. Store ID=1,lang=1.
In maintenance mode, but I believe the webservice is still exposed. 
Using Cloudflare.

We are on a ‘free’ account until I can be sure this is going to work, at which point I will trim the subscriber lists to remove dupes and purchase a subscription.  Disappointed there aren't any logs - how do I see what is happening?

Just concentrating on email at the moment, not the other features or product upload.

Does anyone have Prestashop sync working?
