State/country picklist aren't updated in Salesforce

[CnP.Support.AM]

Good day!

We noticed that you have upgraded to latest versions of our apps yesterday. We reviewed and didn't find any posting errors related to State/Country picklist in your instance.

Let us know if we can be of any further assistance.

Thanks,

State/country picklist aren't updated, causing the posting error, is that our C&P settings inside our SF instance are multiple versions out of date and need to upgraded as soon as possible, to keep interruptions such as this issue from happening in the future. Anyone know how to do this.
