Another message from PayPal in regards to TLS 1.2

My clients are receiving messages from PayPal about another upgrade they are making. I have searched and studied this but I can not figure out if I need to change anything in my eCart setups that use PayPal Advanced.

Here is part of their message...

"Our records indicate your current PayPal integration is utilizing a version that is less than TLS 1.2. With the deadline for this security upgrade currently set at June 30, 2018, you will need to act immediately to upgrade your PayPal integration(s) to utilize TLS 1.2 cryptographic protocol PRIOR to this date.

Failure to upgrade your integration by June 30, 2018 will lead to an inability to connect to PayPal for processing customer transactions. For further information on the TLS 1.2 upgrade, please bookmark the TLS 1.2 Upgrade Microsite page and visit frequently to ensure you are armed with the most current information..."

The link they provided is https://www.paypal-notice.com/en/TLS-1.2-and-HTTP1.1-Upgrade/

Is there something I need to change in my WA eCart files?

These sites are using the PayPal Advanced setup where the user doesn't leave the site when making a payment with a credit card. The sites do have an SSL installed and when viewing the certificate's details through the browser, it says they are using TLS 1.2. So I thought maybe it might be something in the WA code that I need to update. Some of these sites where setup a couple years ago.

Thanks for any help you can provide me.
