Ea play app won't open on ps4

Hey @jcsweeks can you try the following steps to see if they help: 

Restart your console:

• Turn off your console and then turn it back on.

Make sure your game software is up to date:

• Go to the PlayStation home screen. 
• Highlight the game you're playing and press the Options button on your controller.
• Select "Check For Update" and install any updates that are available.

Make sure your PS4's system software has the most recent update:

• Select Settings at the top of the PlayStation home screen.
• Choose "System Software Update" and allow any system updates to install.
• Reboot your PlayStation 4.

Clear your PS4's cache:

The PlayStation 4 doesn't actually have a cache to clear. That said: It never hurts to power down/power up your console if you're encountering performance issues in the console. 

1. Press and hold the PlayStation button on your controller. 
2. Select "Turn Off PS4". 
3. Let the PlayStation 4 to fully power down and wait for 10 to 20 seconds.
4. Restart the PlayStation 4.
