No need to collect bags or go through immigration, it does sound like that may have changed now but we didn't and if we had flown this year flight was altered and thing we was down to an hour.

Sounds like this was the return leg - in that case no bags or immigration and 45 minutes - 1 hour may be fine.
But on the way out you will need to collect and recheck bags, and go through immigration. I’d be looking at 2-3 hours layover at Atlanta, it’s a big airport.
