i'm getting mixed signals if my account is egible
I recently wanted to play back on my PlayStation account and with cross-progression it seemed like a perfect time. I did find out that my PlayStation account was still linked to the wrong ea account. With some help of ea support I tracked the original ea account of my PlayStation account. But I needed to wait a bit before I could link it back. I decided to level my account on my pc already and left my other account in the dust because I'd spend money on my PlayStation account. It's been about a week and my account still didn't get transferred, so asked to support. (this is after I linked my PS account to it) They said because I triggered the cross-progress prompt before the original account was linked back that I would not receive cross-progression for my pc. Thus, I came here to ask because the previous guy that helped link the accounts together said it was fine, and I really hope he was right.
It sounds like the issue is that your PC and PSN accounts are linked to different EA accounts. Both needed to be on the same EA account before the merge happened.
