Form 3115 to Ogden UT Not showing delivered

I had to paper file my 2024 returns since Form 3115 was involved. Sent three separate envelopes by USPS priority mail - 1) IRS Federal return along with Form 3115, 2) State tax returns, 3) Form 3115 separately to the Ogden, UT address.

 

USPS tracking shows the first two successfully delivered but the Form 3115 to Ogden, UT is stuck at "In Transit to Next Facility" since 4/20. I have opened the missing mail search request with USPS but there has been no update on it. Can someone share their experience on what do to in this situation? Is it possible it was delivered but USPS didn't scan it while delivering it? Should I send another copy of Form 3115 to IRS Ogden UT address?
