Constant Ultimate Team Disconnections Resulting in Unfair Losses and Warnings

Hi there. We're not aware of any issues with the servers currently. If you'd like to test your connection, run the Connection Quality Report and get me a screenshot of the results. 

Also, it sounds like you might be on a wireless connection. Disconnects and lag are going to be far more common on wireless than wired. That should improve your connection if you can switch.
