From General Instruction of the Roman Messal
It is most desirable that the faithful, just as the priest himself is bound to do, receive the Lordβs Body from hosts consecrated at the same Mass and that, in the instances when it is permitted, they partake of the chalice (cf. no. 283), so that even by means of the signs Communion will stand out more clearly as a participation in the sacrifice actually being celebrated.[73]
This is not a recommendation from Pope Francis, but a valid option from the Congregation for Divine Worship and the Discipline of the Sacraments, so the Pope (obviously) approves it.
Communion under both species is most desiderable, but it often has some pratical difficulties in performing this option (OGMR 283).
The diocesan Bishop may establish norms for Communion under both kinds for his own diocese, which are also to be observed in churches of religious and at celebrations with small groups. The diocesan Bishop is also given the faculty to permit Communion under both kinds whenever it may seem appropriate to the priest to whom, as its own shepherd, a community has been entrusted, provided that the faithful have been well instructed and there is no danger of profanation of the Sacrament or of the riteβs becoming difficult because of the large number of participants or some other reason.
