App loses data the website has

ALongHolder 3 years ago in iPhone App 0

I recently had to delete the app from my iPhone because it would never open. I reloaded it from the App Store and It has created a mess. While it was able to log me back on ( I forgot my password) I have lost all the authors I follow and my portfolios even though the website has them. Adding insult to injury, every time I try to post a comment under the username I have always used, it tells me that that name is already in use.
