I have to switch between using the app and web browser. On the app I can't reply back to new message request and I can't load up my messages, but on the browser I can. On the browser I can't get onto my account profile which is another reason I use the app. Now as of today I re-download the app, then deleted my account and unlinked my Facebook just so I can make a new account. Once I made my new account I logged in fine with the web, but not my app is erroring and won't let me sign in.
