Had the planned route in the FMS. When I received the CPDLC I missed the new route. I had reviewed several routes via the weather application. The route looked familiar and I didn't notice the route change.I have not flown in 5 months. Flight Attendants checked in while I was checking the clearance via CPDLC.The ability to print CPDLC on the ACARS would have trapped my error.
Air carrier pilot reported a track heading deviation during climbout.  Pilot cited distraction and lack of flying as a contributing factors.
