Can not set the monthly view as default. Was always used to viewing the calendar at a monthly glace automatically without having to change it every time.
Icons for Birthdays, anniversaries , dr's.. don't automatically appear on calendar..they are not visible in the monthly view unless that respective date is viewed.

If there are several events on one day..you can not view them and again have to click on that day
Please give us the old calendar features back

Oh & all the items I input on my yahoo calendar drop off my iphone
