I've had the Messenger app used with Facebook for about 3 months now, however there is one problem that I've had for a long time now - the profile pictures never update (except my own one). So if I don't reset the app often enough (let's say 2 months) then I'll be left with many outdated icons that should have uupdated themselves weeks ago but haven't. Clearing the cache does nothing, and since you can't log out of Messenger, you have to manually clear your data. And within a day or so you'll see more outdated icons on my Moto G. Is this a bug with my phone or the version of Messenger? Nothing seems to fix this issue except a reset of the app. Has anyone got anything to suggest?
