Hello there @The3xector0fhel ,
I would go to your phone settings > App Settings > Click on the Mirror's Edge Companion App > Click on Storage > Clear the Cache > Go back one page and Force Close the App. Then restart your phone and try running the app to see if it will work.
You may also want to try using a different type of connection too. If you were using Wifi, try connecting to your hotspot instead, etc.
Let me know if you get any more errors.
Happy Gaming and Stay Safe!
