Confusion over State Farm billing

Hi all. This is my first time buying insurance and I went through State Farm. I purchased my insurance on June 28th. It didn’t go into effect until July 1st (which is strange, I never knew it could go into effect days after I paid.) Anyway, it’s now the night of June 28th. My app says my bills are due on the 28th, just like I set it up, but says there’s “No bills due right now.” Am I going crazy or is State Farm just really confusing? Did I already pay for all of July’s month and now need to wait for August? It just didn’t make any sense, please help, thank you lol
