No worries. Our Operations team is already aware of these upcoming changes and has our system prepared in advance to ensure a seamless transition. Since E-junkie is centrally-managed software, we handle back-end integration details like this for you, so no action would be required on your part; we'll have it all taken care of at our end.
We're not sure why this latest round of PayPal notifications imply some upgrade is still required, as we've been fully compliant at our end for quite some time already, so we have asked our contacts there for clarification. At this point, we can only guess they may be probing your own site domain under a mistaken presumption you have ecommerce software installed on your own server that would need to be compliant, rather than using centrally-managed "software as a service" (SaaS) such as E-junkie that handles such technical concerns for you independently of your site's server.
