I got in with about that much shadowing, to be fair. Did you call your state schools and see if they are willing to give feedback? I would expect something unless its just COVID and lateness.
Did you apply with a DO letter?
it is strange you received no interviews...
Apply earlier and to more schools
For MD:
Georgetown
George Washington, Albany
Drexel
Tulane
Temple
For DO you should add Touro Harlem, Rocky Vista, Burral or whatever, AZCOM
