Its a really hard one to track as I have been in contact with several people with the issue and they have it sometimes, then can connect at other times. It doesnt seem to have anything to do with our servers....we are aware of it and trying to figure it out but this one is tough as its infrequent and seems to just work sometimes and not work other times.
I just bought the PvZ GW2 and I too have the 'must be signed into PSN' problem. Clearly this is a problem for many. I didn't realize EA games have such problems. Unless there is a fix, i'll have to try to go for a refund as well as carefully consider if I buy EA games in the future. Please let me know if there is a fix.
Community Manager@jeffersonjchoi Have you checked that you are signed into the PSN? The accepted solution in this thread has worked for many: https://answers.ea.com/t5/PvZ-Garden-Warfare-1/You-must-be-signed-in-to-quot-psn-quot-to-continue/td-p/4713113
