Stop logging me out and and changing my profile picture

Hi, sorry to read that you're having issues, hopefully I can clarify/help. 

For the Avatar, we recently made a change so that you can use the custom avatars from your EA profile.
To update this (and you can use a pic from the forum avatars, please check the steps here: Introducing custom avatars. | EA Forums - 12048417 

For the logouts, you will naturally get timed out from time to time, but if it's happening more frequently than it should, perhaps clearing your cache will help. 

In Chrome, click the 3 dots in the top right, choose "Delete browsing data", then go to the advanced tab, check just Cached images and files, and delete. Hopefully this will lead to a smoother experience for you.
