[JUN YE]

Dear 

Our client as the same issue like this conversation

https://groups.google.com/g/certificate-transparency/c/otRk_9FZTEA

we also received the same alert

---------------------------------------------------

Your app has been identified as having a dependency on com.appmattus.certificatetransparency. Due to the v2 log list turndown on November 17, 2022, you need to upgrade to use v3 log list to avoid potential app crashes.

A workaround is available before the fix is merged and released. You are advised to apply the workaround in your app and publish a new version to Google Play as soon as possible.

The v2 log list endpoints will serve the v3 log list, which is backward compatible with v2, for 90 days starting on November 17, 2022. The v2 log list endpoints will start returning 404 on February 15, 2023.

 -------------------------------------------------------------------------------------------------------------------------------

our client need your help and guidance for our Live apps. 

our client unable to find the  Dependency which is using this "com.appmattus.certificatetransparency"  as I have searched my whole project/ modules. Please guide me regarding the following question:

1) How can I find which dependency is using "com.appmattus.certificatetransparency"?

2) What will be the impact if we don't upgrade to V3 from V2? will it cause crashes in the front-end app?

I am Waiting for your kind response.

As your response as before, let me confirm how to provide our dependency lists worked out by gradlew to you, and would you advise any solution for resolve our issue?

Hello Jun Ye,

Does the Play Console account own more than one app? The message was sent to the developer accounts with any app being impacted. To protect your client's privacy, I will follow up in a separate email to get the list of package IDs.

The impact depends on how your dependency package handles the exception from com.appmattus.certificatetransparency.

Cheers,
Roger on behalf of the Google CT Team
