Which client functionality are you experiencing this bug with? Other (Please Describe)
Please describe EA App does not stay minimised to system tray
When did this happen? (dd.mm.yy hh:mm) Every time
Summarize your bug EA App does not stay minimised to system tray and opens by itself unnecessarily.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Install EA App. Buy EA game in Steam. Run game. Behold as the EA App pointlessly opens a log-in pop-up. Play game. Close game. Behold again how the EA App has decided to open by itself. Manually minimise EA App.
What happens when the bug occurs? EA App interferes with other processes, such as Steam Link. It steals focus. Break things. Does the opposite of being usable and transparent.
What do you expect to see? I expect to NOT SEE the EA App, because it is minimised to the System Tray. That is where it should stay until I open it again. For more information, ask ALL THE OTHER apps that obey the System Tray usability rules perfectly.

The EA App has two very irritating and entirely non-sensical behaviours:

1. It opens up from the system tray for NO REASON when you run an EA game purchased in Steam. The app should STAY MINIMISED link Steam does - like ALL OTHER apps do. There's no reason to see it pop up.
   
   
2. It opens from the system tray for NO REASON when you close an EA game which was run via Steam. This app should stay minimised.

This behaviour:

• frequently sabotages Steam Link functionality, because it steals focus.
• often causes the EA game to run minimised, which means that the user has to manually maximise, which often breaks full-screen functionality in the app.
• gets in the way of "play". You know, "EA PLAY".

This behaviour is also made 100% worse by the VERY long-running bug by which the EA App is completely UNABLE to retain its log-in cookie or whatever. So if you close the app and run it again, or you just BOOT the computer, you will have to log-in manually again.

So the solution is simple: 

1. Fix the log-in bug. It's been a couple of years, so I am sure the patch is almost read to roll out.
2. Do all your DRM checking in the background when an EA game is evoked by Steam.
3. Obey the user's settings and KEEP THE APP MINIMISED unless the user decides to open it up again.  The user does NOT need to see the app unless the user wants to.

Will it happen? Issue 1) has been known about for ages, but it has never been fixed.

Will I buy more EA games on PC? Definitely not.
