Hi, we think the stickies sit around on the android app forever. The only way to get rid of them is to delete it and reinstall it. Sorry about that. It's on the list of things to fix. The problem with fixes to the apps is that you have to go through the whole rigmarole of specifying the fixes, getting them developed, then submitting the app to the app stores for an update, all of which take time. It's not like the site where we can just fix things overnight. Sorry for the delay. It is on the list. I'd advise using the mobile site if the stickies problem is very annoying for you. Sorry we can't be more immediate help.
have figured out if you go to installed apps on your phone ( mine is in settings>applications) then wipe data it'll wipe the stickies when they build up and you just log in again, loads and loads faster than deleting and reinstalling the app
