Talking Aosp calender sync WORKING as it should!!

If you have calender sync problems (like i had on every aosp rom i flashed) get an app called CaLDav on playstore (it´s not free) install and choose too add a google account, login to google accept and voila your entire calender for years even, shows up again like magic
never worked on aosp even with aosp calender sync zip flashed but this one does the trick
