Ok, since you asked… The first statement presented in the Dubia reads as follows:
It is asked whether, following the affirmations of Amoris Laetitia (300-305), it has now become possible to grant absolution in the sacrament of penance and thus to admit to holy Communion a person who, while bound by a valid marital bond, lives together with a different person more uxorio without fulfilling the conditions provided for by Familiaris Consortio, 84, and subsequently reaffirmed by Reconciliatio et Paenitentia, 34, and Sacramentum Caritatis, 29. Can the expression “in certain cases” found in Note 351 (305) of the exhortation Amoris Laetitia be applied to divorced persons who are in a new union and who continue to live more uxorio?
This is an excellent question that requires clarification, especially the latter part that asks whether “in certain cases” found in Note 351 (305) of AL can be applied to divorced persons who are in a new union and who do not live in continence. My sister is in an irregular union, but she is not divorced and civilly remarried. Rather, she is a fallen away Catholic who married a non-Catholic outside the Church. Certainly, she could, following discernment and accompaniment, repent and return to the Church, which could include the help of the sacraments. In other words, Note 351 in AL can be viewed in an orthodox manner in the example I provided, but if “in certain cases” refers to those who are divorced and civilly remarried who do not live as brother and sister, then Note 351 appears to be heterodox because now the Church would be admitting to Holy Communion those who are in a state of perpetual adultery; hence, the question being asked.
