big fan for RTM, so had astrid with no hesitance. then installed pure calendar by following friends' recommendation. But i realized one problem, astrid cannot automatically sync with RTM as i set up. I m certain that i had astrid "Auto-Synchronize" on (hourly) , and have android os "background data" & "auto-sync" on also. anyone can give me some help? it drives me nut that I have to manually sync every after a while.
