Activision released a new FAQ in this regard:
“In consideration to not increase the burden on the primary server, so we decided to postpone the launch of ELITE mobile app until the server is stable and the users can access it easily.
“We will soon provide additional information on the latest situation and launched ELITE soon as we are confident that users will get the ‘gaming experience’ is superb.”
Last week Activision stated that the tremendous amount of demand as the root of the problem and announced that the entire premium subscribers will get free access for 30 days as compensation. Activision also announced it will provide users ELITE “custom iOS and Android applications for smartphones and tablets”.
