The union of the common accounts of the three trackers (SceneFZ, MyXZ and ICE) was made on 04-07-2020. From now on, you can access any of the three domains with your oldest account, provided that the two or three common accounts had the same email at the time of the merger. If you can't access your account in the other domains, use the password of the current account, or recover password, in case you don't remember it. In the near future, the transition to the new domain will be made, without any change on your part.
