Apple Worldwide Developer Relations Intermediate Certificate updates

Changes per 1/28/21

https://developer.apple.com/support/wwdr-intermediate-certificate/

Currently working on updating to Xcode 12, but might need to submit a release before that happens.

We have certs that expire at the end of the year, but still running Xcode 11.3.1

Does anyone know if there will be any issues submitting with these new changes? I know it says for new certificates.

Also the push cert expires this month. So if I renew it, still under 11.3.1 will that cause any issues with users receiving push notifications?
