Re: Can´t transfer the sims expansion to child account
@rumpenstink I don't know why child accounts are so difficult to manage right now; hopefully EA will find a way to address that in the future. Until that happens though, your best bet going forward might be to buy a physical copy of each Sims 4 pack you want your child to have. Even if it's just a code in a box, you can manually add that code to the account rather than having to go through this whole process with EA support.
Sorry I don't have a better answer.
