So what are those problems that you see?
The imprecise language that Pope Francis uses. Personally I can see that he is at least inspired by, if not directly guided by movements like Communion and Liberation, but that's because I'm involved in that movement. For others in the Church, much less outside, who aren't his choice of words and emphasis on pastoral concerns, seemingly (note the word seemingly) devoid of orthodoxy can be and are a source of scandal. In CL there are certain unspoken "givens" regarding orthodoxy, so, for example when we speak of the need for an "encounter with Christ" and a rejection of "moralistic" practices we don't speak of the rejection of the Rosary, or the veneration of saints, or any rejection of anything uniquely Catholic, as has been ascribed (falsely) to Pope Francis when he has allegedly "condemned" those who have a special devotion to such practices. However His Holiness needs to realize the entire Church doesn't participate in CL, and thus doesn't understand where he comes from when he speaks in such a manner. He needs to respect the office he holds more by either being more careful with the words he uses in public or shutting up.
The ongoing sex abuse scandal. This is a problem not because the Church isn't addressing it, but because new allegations keep surfacing. "New" in the sense that they are just coming to light, even though most still occurred decades ago. This presents a problem because of the financial drain it presents as well as another ongoing source of scandal. Unfortunately I don't know what more can be done at this point than pray for the Church and continue to compensate those who were indeed harmed by this evil. It's an ongoing problem.
The "liberal" interpretation of Vatican II. Unfortunately the confusion that resulted from the council (or really the confused interpretation of it) has caused many to leave the Church, much less not caused a new influx as was the hope. Re-education of everyone in the Church about what the council did (and did not do) is necessary at this point. But the feel-good false ecumenical leadership in the US particularly (although around the world too) prevents this return to orthodoxy for the most part because they were swept up in the media generated furvor over the council in the 60's. They bought into the notions of "priests will be able to marry in 10 years" and "psychology will cure all the problems of the church" as well as similar media driven expectations of today such as "birth control is coming to Catholics too" or "women can be priests soon". The same people caught up in that hype are in charge now. But all hope isn't lost, as the new generation of priests coming in are far more orthodox. The old hippie priests and nuns are literally dying out. However still remain a problem today. Which brings me to my last problem.
The continued, scandalous permission of priests and bishops allowing their parishioners, the sheep they are responsible for, to continue to receive the Eucharist when they know they either support abortion, gay "marriage" and contraception legistlatively or through their vote, or through their political affiliation. This is a scandal, and it is an evil not only on the Ordinary involved, but for those who are so deceived. Again, my hope is that the current class of priests coming in will put a stop to this in the future, for the sake of all souls involved.
