While descending on the ZZZZZ2 arrival and approaching the ZZZZZ intersection; PM was distracted by radio calls and clearances. Upon reaching ZZZZZ intersection PM identified that we were approximately 500 feet high crossing the way point. PF corrected by increasing rate of descent to reach 8;000 feet. Around the time that we were leveling off at 8;000 feet received clearance to 7;000 feet. While descending we identified that conditions had changed and that a full ILS approach brief would be warranted. Approaching 7;000 feet; ATC cleared up to descend to 4;000 feet and it was not noticed that the aircraft had captured the altitude after 4;000 feet was set. ATC later gave a clearance to descend to 4;000 feet and we identified our error and quickly initiated our descent.Both the PF and PM have been doing little flying over the last several months due to the COVID 19 pandemic. As such it had been some time since last arriving in ZZZ. As well as the short duration of flight and the changing weather conditions led to being behind the aircraft.Making more time by asking ATC for vectors in order to brief the approach. Briefing the full approach even when not expecting IMC conditions.
Air carrier Captain reported not making a crossing restriction during arrival and cited lack of flying as a contributing factor.
