There was NEO node syncing problems and swap portal went down, now team is rebuilding it so it won't happen again. You have to wait for swap to be reopen, but there is no date yet, so stay tuned.
Thanks.
I have just sent an email to
swap@effect.ai as stated in the swapping website. Let us see if they come back with some solution.
If anyone know if there is a way to swap tokens, please let me know.
