I sent an email asking about the M37 and P66 situation a couple of days ago.
The email response from FTDNA did not make any promises this time. It merely said that M37 and P66 proved more difficult to find than they had anticipated. They are working on the problem and hope to have results soon.
so in the last 6 months ftdna has been unable to perform as advertised.
where are my snp results?
It's not just FTDNA. Apparently, SNPs are simply more difficult to detect properly than research papers led us to believe. Here is a complaint that came over a prominent genetics mailing list today:

Several weeks ago I reported here an unusual result at P25 from Ethnoancestry. The report was that I had no C-type allele at P25. The conclusion was that my P25 SNP was of the AAA type, not seen in any other man. This conclusion was reviewed and confirmed by Ethnoancestry. Several days ago I reported on another series of tests on a distant cousin in regard to S21. The cousin was found to be S21-, which caused a review of my test and I was changed from S21+ to S21-. Now at P25 my result has changed also. The cousin was found to be P25+; I was retested and found to be P25-. Previously I was reported to be M269+. Now it seems that I have no A-type allele The cousin has not been tested at M269, but the whole bunch of us are strikingly close to the STR R1b modal haplotype.
This error at P25 appears to be totally unrelated to the S21 error. Perhaps I am error-prone.
This is a real confidence shaker, but could turn out to be quite a good thing for Beatty genealogy. As David F noted, if we have errors it is GOOD to have them discovered. How many more? I need to decide what else needs to be checked.

I am coming to the conclusion that research results with tables of haplogroups are just as shaky as this, except that researchers don't bother double-checking their results because they can just attribute it to "statistical variation."
