I also have no pop up or any type of message on the main menu screen for the Login Events making it impossible to claim any reward. I'm going to tag @EA_Cade for help since this is a limited timed event and we are unable to claim rewards even though we are logging in and participating as instructed.
I've attached a picture of my main menu after logging in several times today showing there is no Login Event showing for me. I hope the team fixes this error and credits our accounts for the reward items that we are unable to claim.
