In an Activision Support post, the publisher is going through with pulling the plug for all GHTV in-game purchased tracks. Check the post below for detailed info. Players can continue to use their Hero Cash and items on hand as well as enjoy GHTV and all content in the game mode, including Premium Shows through November 30, 2018. Players will no longer be able to use Hero Cash or items as of the GHTV sunset date of December 1, 2018.
“We want to thank you for being valued fans and let you know that as of December 1, 2018, the GHTV mode within Guitar Hero Live will no longer be available to play. On that date, we will terminate the service for GHTV and servers will be shut down. Console versions of the GH Live mode will continue to operate as usual.
As of June 1, 2018, iOS versions of the Guitar Hero Live game for mobile will no longer be available for download via the app store. However, if you currently own the app and have it installed on your device, you can continue to play the GH Live mode on your installed device. Please note: if you update your iOS software, the app may no longer be supported.
Additionally, on June 1, 2018, all GHTV in-game purchases will be turned off. Players can continue to use their Hero Cash and items on hand until the GHTV sunset date of December 1, 2018.
Thank you for playing GHTV, and head to GH Live mode on console to continue to play.”
