Cloudflare caching plugin

We recently removed problem caching plugins and are now using a single caching plugin – the official Cloudflare plugin.

Sinced the change we have seen problems with our Google shopping feed having products blocked because of “mismatched product price” – Google are picking up cached prices in the wrong currency.

Are Curcy pro settings are as follows:
Enable = on
Fixed Price = off
Use SESSION = off
Switch Currency by JS = off
Use cache plugin = Override by AJAX
Reload filter price = off
Loading price mask = off
Bot currency = Default currency

Please advise on the correct settings to apply to solve this problem. Thanks.
