Another update: The "lost plate" form I filed at the local DMV was rejected and sent back with a "Notice of Unprocessed Payment". Under Other: If BOTH plates were lost or stolen the same configuration cannot be reissued on any plate type.
I called the Sacramento office (916-657-8035) - prepare for a long wait. The Sac office basically said the local DMV offices have no clue. The Dec 24, 2021 date was when DMV recognized/approved the new plates but NOT when they were made or mailed. They told me I needed to wait 90 days not 60 days before calling back. The wait continues...... (ordered Aug 11, 2021)
