Coming Soon: Y-DNA Haplogroups for Family Finder

[Riverman]

AFAIK, MyHeritage has no mtDNA SNPs in their Raw Data.    Unless there is another version of MH raw data that FTDNA and MH have not released.

Ancestry has only a few, so FTDNA will have limited success with those uploads.
23andMe has about 4000 mtDNA SNPs, so FTDNA should do okay there, but probably not any better than 23andMe itself.

I have not seen any numbers as to how many mtDNA SNPs are in a complete FTDNA Family Finder Raw Data.

So FTDNA always had Y-DNA and mtDNA SNPs in their raw data? Then why when you uploaded to Cladefinder and Jameslick, didn't work and wasn't found them?

But if they are adding those SNPs now, Couldn't they also do that with MH and get the mtDNA when you transfer it to FTDNA? I mean, MH is processed by the FTDNA lab.

FTDNA always tested yDNA and mtDNA, they just deliberately removed it, so that people use their specialised products. That's a big policy change. MyHeritage has the same chip in usage, that's why they are most compatible and comparable.
