I don't know why, but since the Mango update (and both before and after the 3.3 Weave update, though worse after the 3.3 update) Weave has been horrifically slow - the "loading dots" seem to move across the screen continuously forever, sometimes only 1 dot will show for some reason, and even when they're done my articles haven't necessarily updated. Any idea why this is the case? I don't want to uninstall and re-install because I don't want to lose all of my custom feeds, but is this what I'll have to do?
