CA polymerizes in the presence of water so it is is possible that humidity is affecting it. Using wood that isn’t dry enough could be a problem too. If you can check the moisture content of your wood that may help you determine if that could be a factor. When applying I make one pass and stop. I don’t got back and forth. If I feel a pull from the paper towel, I didn’t apply quickly enough. I use accelerator after each coat to make sure that it sets before I apply the next coat. I rarely use medium or thick CA because when I do, I almost always have ridges or pits that causes me to sand it back severely or have to start over. Even when I use a thicker CA, I sand (400 or 600 grit) and apply one or two last coats of thin to give the smoothest finish possible. After the last coat, I will lightly sand at 600 or 800 one more time to make sure that there are no pits or ridges before polishing. I have never found a need to use anything over 1000 grit (I have micromesh but have never used it). The polishing compound basically accomplishes a glass smooth finish.

BTW, I doubt that natural oils in the wood should be that much of a problem. Some people actually use a cloth or paper towel dampened with BLO as a lubricant to apply the CA. I have never tried this but I am sure that you can find examples of that online.
