When should I start worrying about ACT scores being received?

I’m sure this has been asked many times before; however, I was unable to find a clear answer out there already. I sent in my ACT scores last Thursday to my Early Action schools (I know I should have probably sent them in earlier, whoops). I checked on the status of one of my Early Action applications today, and it said my ACT scores had not yet been received.
When should I get worried about this… aka how long does it normally take for them to be received?
Also, do they need to be received before the application deadline (November 1st) or is it ok if they come in a little later?

ACT doesn’t “send”. They simply make it available for the college to download. Not all schools do it every day.
