As a broad indication of the effects of measurement error in 23andme, ancestry analysis for two identical twins is below. It suggests the decimal point isn’t yet justified. (Their Neanderthal ancestry estimates are also off by 0.1% from each other.)

OK, I don’t understand how identical twins could be different at all. They’re supposed to have the same DNA, that means that they would have the exact same SNPs.
Unless it is due to measurement error. Of course, that means that the same person tested twice would give different results each time.
info@promethease.com would be happy to help with a more detailed analysis of the raw data.
