Original tests both done on FamilyTreeDNA (May 2010 and Oct 2016), both uploaded to GEDMatch and both transferred to MyHeritage.
Actual relationship 2nd cousins.
FamilyTreeDNA:
Predicted relationship 2nd to 3rd cousin sharing a total of 144cMs, largest segment 19 cMs
Looking at only those segments over 7cMs this reduces to a total of 96 cMs over 7 segments (including a 10cMs X chromosome match)

This maternal cousin does show up on the MyHeritage match lists for my two maternal aunts, both
sharing 5.5%, 395cMs total, largest 63cMs, one with 14 segments, the other with 18.
But nowhere to be found on my match list, nor I on hers.
Looking at the FTDNA Chromosome Browser picture for my 2nd cousin compared to myself and the maternal aunts clearly shows at least three segments where I match at least one of the aunts (chr. 1,2,5) at which spots those matches total about 52cMs, well above what I'd consider a match from MyHeritage
