If Francis has not changed doctrine then the divorced and remarried cannot receive the Sacraments whilst living more uxorio, that is the doctrine. If the bishops are as you say pastoral teachers then they can only reiterate this doctrine and try to persuade such couples to give up their sexual relationship, repent and amend their lives.
If on the other hand as some bishops have declared, such couples can continue in their adulterous relationship and at the same time receive the Sacraments of Penance and the Eucharist then the doctrine has definitely changed. So which is it?
Two directly opposed interpretations of AL are doing the rounds and the Pope stubbornly refuses to clarify which is the correct one. That is why the Cardinals sent him their dubia, that is why scholars and academics from around the world have pointed out to him the detrimental effect that AL is having in the Church. Pastorality means safeguarding the sheep not letting them wander wherever they like.
