[MCU] Captain America and the Snap

So Cap had already lived through the snap when he fought Thanos originally. When he went back in the past and lived through to the present day, was he still affected when Thanos snapped?

He probably didn't live through a second snap. He spent the rest of his life in an alternate time line before coming back to ours to give Sam back the shield, just not on the pad where they expected him. 

He most likely just waited until Peggy passed away in 2016 or so before coming back to 2023, so he bypassed the second snap entirely.
