The Echoes of Mana emergency maintenance was supposed to have ended 27 April 2022, 07:30 UTC. However, as you can see, they’ve extended it further, and potentially longer depending on what happens. As it is, after pre-downloads were made available, some have already made 1-star reviews complaining their inability to play.
At time of writing, neither the English or Japanese Twitter accounts have made an update regarding the extended maintenance. We should be able to expect compensation to follow, once they’ve settled on whatever it is that’s going on.
