That's a shame, I made good use of it while it lasted!

Is anybody else having a problem looking at Common Ancestors?  I cannot get past the first page.

The 20cM shared match threshold hides so much it can really stop research stone dead.

I have a mystery 42cM match, he shares 604cM with 'SC' so I see them as shared matches on my account but I only share 15 with SC so the mystery match uses his account but doesn't see the connection. He also misses other matches to SC because of the 20cM threshold.

Thankfully we shared our dna results and I've been able to identify 7 mutual matches so far that the 20cM threshold manage to hide even when analysing match lists of each person individually. The papertrail of my mystery match doesn't line up with the DNA and I suspect an NPE somewhere. All 7 matches trace back to the same common ancestor which seems to confirm my suspicions but had we not shared our results my mystery match would still be in the dark.

I think that Ancestry has updated their system a bit.

If I have a Thruline or Common Ancestor that has a suggested pathway that does not compute I add the related DNA Match to a Mystery Group and add text “Odd Thruline” to the Matches Note.

Since your post I have revisited three such Matches and each now has a Thruline that is now valid.

Yes, I am now getting all the Common Ancestors again and a few new ones.
