So if like me you upgraded your iPhone to iOS 8 then you may find that you have a few problems with your apps. One problem I got was with the Twitter app which did not work properly after upgrading.
I have 3 Twitter accounts that I manage on my iPhone and when I tried using the Twitter app again after upgrading, only one of these accounts was working. The two others just showed up as blank profiles and seemed to be trying to load. I tried uninstalling the app and reinstalling but it just downloaded it from the cloud with the same settings.
I did find a way to fix it though which was to sign out of the two accounts that were not working (go to the Me button and select settings) and then to add the accounts back in. This seemed to work OK.
There do seem to be a number of apps that don’t work on iOS 8 so if you haven’t yet upgraded then I would recommend waiting a bit. I usually do but my email was crashing so I thought it would work better if I upgraded.
