Let me add that the circles are exactly at the same spot than anomalies when "Show anomalies" option is checked, they just change of size... So the problem is just that we cannot hide the anomalies anymore on line charts!
The bug raised with the Engineering team has confirmed that the fix of this issue would be released in April. Please let me know if there is anything else I may assist you with and I would be glad to take it forward?
Unfortunately that seems to have no effect. Below I have chosen the max items allowed of 19, although because of my date selection of Mar 14-Apr 1, it seems Adobe Analytics has decided Mar 15 and 17 have anomalies for the Visits metric.
I suspect this is a bug, and have opened a ticket with ClientCare.
