I sent my scores to one UC campus with rush shipping on Sunday...how do I know they were received?

I sent all my SAT scores to the UC Davis campus with rush shipping on Sunday. I have received emails from UCLA. UCSC, and UCR to set up my portal. But all those campuses say my test scores have not yet been received. What should I do? I received a receipt from Collegeboard.

I thought if I send my scores to one campus they will share the info with all the campuses I applied to.

Each campus will receive the scores but even Rushing the score reports, it takes time for the schools to download them into your file. I would give it at least another week before coming concerned.
