If you’re referring to the city in English you would say “bo-LO-nya” to approximate the original. I’ve heard it on the radio/podcasts before. It’s not very commonly referenced so trying to get closer to the original is probably right. Unlike Paris, where you are seen as pretentious if you pronounce it the French way.
You are probably lucky, for now. I’m pretty sure they are rolling it out in waves. Boiling the frog and all that.
