Although more are showing up as large enough to target now, Too Small is replaced by ready, match rate for some lists is way down from before.
Example:
Account ID: 18ce53vuwjg
List ID: 15525
List Size before match: 69044
List Size after match: 9205
This same list that was uploaded directly previously matched far higher than this on the client’s account 2 weeks ago and matched ~47K IDs. I realize the matching process updates match size regularly but I can’t imagine this drastic a change. Yesterday the match size for the same list was in the hundreds so something seems to be up with the match processing.
