Curious as to what is happening with MileagePlus Activity and "Statements".

Prior to 2015, United seemed to batch activity every so often and move them to "Statements"....about every quarter year. It was sometimes a pain as you had to jump around to statements to check on posted activity.

My last Statement was at the end of 2014. All of 2015 activity is still showing up as "Recent Activity". Nice to not have to click around various statements, but surprised they haven't at least batched everything into a 2015 Statement.

Wonder what is the rationale around this.
