I have never heard of bishops suppressing it, because I have never heard of anyone requesting it. In all cases I know of, people who want a mass in Latin want the traditional form.
True, most people who want the mass in Latin want it in the traditional form, but there are some who prefer, or at least like, the new mass in Latin. If memory fails not, George Weigel is one of those, and it is available somewhere in Washington, DC; and the Order of St. John Cantius, which has a few churches in Chicago, is one of the groups that does the new mass in Latin, as well as in English, and (at least until recently), the old mass in Latin (I thought Cardinal Cupich had shut that down, but on the Cantius web site it looks like it still might be going on).
So there is not much of the new mass in Latin to be suppressed, and Pope Francis certainly has not tried to suppress it, and a bishop would have to be extraordinarily ignorant and/or irrational and/or malevolent to want to suppress it---but still:
the Diocese of Alajuela, in the Northern region of Costa Rica, ordered Fr. Sixto Eduardo Varela Santamaría to be suspended from all ministries for six months, and will be sent to a psychological treatment clinic for celebrating in Latin the Mass of the Missal of Pope Paul VI, also known as the Ordinary Form or "Novus Ordo."

I think the new one (is it called novus ordo or something?)
Yes, "novus ordo", or "ordinary form", or "mass of Pope Paul VI" (and, by a few people, spicier names which I will not repeat); in contrast to "vetus ordo", "extraordinary form", or "mass of Pope Gregory ___" --- I can't remember if it is Pope St. Gregory the Great, or one of the later Gregorys around the time of the Council of Trent.
