For a few weeks now it has been impossible to confirm BillionGraves record matches. Except in a few rare cases a BillionGrave match remains unconfirmed/unrejected regardless how many times I try to confirm or reject it.
I don't know if this is related, I no longer see any FindAGrave matches. In my experience the FindAGrave matches are way higher quality than BillionGraves offer and often contains a lot more information.
