Sometimes when I refresh the official twitter app it will only fetch some tweets, not all. The problems happens most often in the morning after my phone has been off (or in aeroplane mode) overnight. Often it either fetches the last 20 tweets or the last 2-4 hours worth. Hitting refresh again still doesn't bring in the missing tweets so I have to use HTC Peep to get them instead. I've tried setting it to automatic, 2 hours, 4 hours, manual etc but it still seems to fail to show all tweets if you haven't used the app for several hours. Is anyone else having this issue or know how to solve it?
