Workspace and grids presets not available ??
Hello,
I’ve just installed (w subscription) Metagrid Pro : tried to import Cubase grid preset, but in the workspace / Grid preset, it’s appear " No Content available".

Anyone can help please ?
Thank you,

Metagrid pro V 1.6.6
Metaserver V5.2.1

The latest Cubase grids are not premium add-ons - they are available for all users. To access the, go to the Content Manager, and in the Workspaces area tap the Import button and select Presets.
