Unclear where we're using the old SDK

We’ve got this message twice now, once on 3rd September and again on 17th September:

Action Required: Upgrade to the latest SDK before November 2, 2024

Dear Valued Customer,

In preparation for the upcoming SDK minimum version policy, we have identified that your application is running a version of the SDK that will be retired. We’re reaching out to ensure that you have time to update to the latest version and distribute it to your users.

Please upgrade your application to use the latest SDK and ensure that it is also distributed to your users.We plan to implement a minimum version schedule on November 2, 2024, for both Meeting and Video SDKs, as shown below.

Meeting SDK for macOS, iOS, and Android
Minimum version: 5.17.5

Meeting SDK for Web
Minimum version: 3.1.2

Meeting SDK for Windows
Minimum version: 5.17.5

Video SDK for Windows, macOS, iOS, and Android
Minimum version: 1.9.6

Video SDK for Web
Minimum version: 1.9.5

Contact Center SDK for iOS and Android
Minimum version: 3.4.0

Contact Center SDK for Web
Minimum version: 2.12.0

To ensure your users are not forced to upgrade again next quarter when we announce the next minimum version, we recommend that you upgrade to the latest SDK now, before November 2, 2024.

Note that the Zoom client also has a similar Zoom Software Quarterly Lifecycle Policy.

Thank you for your partnership as we continually work to make our platform more secure and deliver a better experience for our customers. For further information about our releases, please see our Changelog. Feel free to reach out to the Zoom Developer Support Team if you have any additional questions or need assistance to update your organization.

I have no idea why we’re continuing to receive these, given we’re using SDK 3.8.5. I can’t figure out from the App Marketplace logs where we might be using an old version.

However, the email explicitly mentions: we have identified that your application is running a version of the SDK that will be retired

Is there a way to understand where Zoom thinks we’re using the old SDK? We’d rather not have our applications break on the 2nd November…
