Just making sure everyone else is aware in case this has affected their instance and they may not have noticed yet. I have a flow step in a smart campaign that qualifies if any of 11 values matches. I checked the flow today and noticed that all 11 of those values were strung together as one value. Obviously this means then that the choice condition is only considering one value and not any of 11:
This did not affect choice condition #2 which had 2 values to consider. I also checked in the Next Gen UX and the issue is still present.
I have opened a case with support.
