that same thing is happening to me. it picks and chooses when it wants to work.
I wonder if (at least for me) if this is an issue on my mac bc the ea app will prompt me to enter my mac credentials randomly. sometimes the app will work, sometimes it wont.
the ea app for mac has created the worst experience ive ever had in the 20+ years ive been playing the game franchise.
Origin app has never given me any issues, Ea app has been an absolute nightmare to try to navigate.
and im sure no one wants to have to uninstall a client (ex. ea app) and reinstall client to *fingers crossed* hope that the app works OR have to constantly restart their machine...
