I was referring to the DOS version which is what the majority of 1-2-3 users ever experienced. While the Windows version existed, it took far too long[1] to be released and was quite buggy. By the time Lotus had even a remotely viable Windows product, they were in 3rd place and had mostly bled out their users.

[1] Windows 3.0 came out in mid-1990 and 1-2-3 for Windows came out at the end of 1991. The options to run 1-2-3 for DOS under Windows until then were comically non-viable. When 1-2-3 for Windows came out, it was practically unusable for those who waited and no longer mattered for those who had already switched away.
