Do casters/ranged attackers have disadvantage while within my attack range?

@JeremyECrawford Do casters/ranged attackers have disadvantage while within my attack range? My character uses a polearm for reach.

See the rule on ranged attacks in close combat (PH, 195). The rule is based on being right next to a foe (within 5 ft.), not on reach. #DnD https://t.co/UUDMmiKTwd
