Unless or until they can agree on the meaning of primacy, it's not healing any time soon. The Bishop of Rome has a very clear view of what he thinks primacy is (Bishop of Rome is in charge). The Orthodox Patriarchs have their's (Bishop of Rome just chairs the committee). The Patriarch of the Russian church isn't even the most senior patriarch in the Orthodox communion - that's the Patriarch of Constantinople, and he's already met Francis as Pope too. It's a fundamental difference in opinion over how the church should be organised. One man in charge or a group of men who each have a little fiefdom? A President or a 'Governing Body'?
The WBTS' view of religious freedoms and understanding (heh) of the bible will constantly put them on a collision course with government authority even of the most benign kind. That's very true. The extent and nature of control over adherents the WBTS demands almost guarantees it.
