Psn change country / region?

Well, I recently moved to Poland, so I want to convert my entire Ps4 to Polish, but I have no idea how. I've already checked Playstation.com, but you can't change the country there, only the place of residence.

What should I do?

Unfortunately, this does not work on Playstation, you can change your PS4 to any language, but not the PSN Store and your settings (they remain in German / English etc.)

And what should I do now, e.g. I can't shoot in Gta at Glückstad, or I can't buy Psn tickets here in Poland, but only on Amazon and that kind of stresses out a bit

Unfortunately, you can only do it that way. An alternative would be to create a new account, but it is not a solution
