I have an A1 too, and when the news came out that third-party slicers (like OrcaSlicer, which I was and still am using) were going to be blocked, I set my printer to LAN only mode. I wouldn't recommend a Bambu to newbies to 3D printing anymore, but I'm stuck with mine and it has been printing ok. Like any printer, it struggles with overhangs and such, it's not always a magic "it just works" experience".
