As of 2.27 the aggregation from weeks to months in analytics was changed: weeks are attributed to the month where they have four days or more. But we are experiencing some unexpected behavior in 2.28. As an example here I paste a row extracted from _periodstructure table in demo server:
(We have checked that period type is set to ISO8601, so Monday is the first day in the week)
Here there are two things:
2017W13 is actually from 2017-03-27 to 2017-04-02 in ISO8601.
This week is attributed to April, which would be wrong even if the week were from 2017-03-28 to 2017-04-03.
Is it the expected behavior? Maybe am I missing some configuration parameter?
Thanks in advance,
