high error rates for SKProductsRequests

Has anyone else seen high error rates for SKProductsRequests? 5% to 10% of the time, I'm unable to present products to my users because SKProductsRequests are failing, even with some retry logic in there. This is costing my business serious revenue and appears to have been happening for as long as my app has been in the Store.

When looking at the error, it tends to be a timeout. Meanwhile, other network requests in my app work just fine.

Thank you

David
