Provisioning profile doesn't update to include device when new registration finishes processed

We enrolled in the Developer Program three months ago. We understand that there is a 24-72 hour delay for new device registration once the total count exceeds 10 (https://developer.apple.com/help/account/reference/device-registration-updates/). However, after this process is complete, we need to register the device again (via Fastlane register) to update the provisioning profile with the new device information.

Our questions are:

  1. Since this delay only occurs with new memberships, when will new device registrations no longer introduce extra processing time?
  2. What are the best practices for device registration before this transition period ends?
