Lucky you, people getting the i2501 are still unable to even complete the Transfer. :/
After linking the Chat support to this thread, they said they are "aware of the issue" and are "investigating" it... Not sure how long they will be "investigating" for or if they actually are, but meh...They were like "You can still play on the old world until the Transfer is done" ... Sure, but my bud (who's the one stuck in the "old" world) can't play with me because of that, and we want to progress together. Duh.
But I'm glad to hear at least some people are now able to get in-game and play, good luck to you (hopefully you won't meet any other issues)!
