I reiceived my Spark yesterday, and I'm very happy with. But during the activation, and the followed first setting, I enable to block flying without a GPS signal. I wanted to be careful. But know I feel ready to try indoor flight, but I can't found the setting to re-enable flying without GPS fix.

Disable the beginner mode in DJI Go 4 app. You click "go Fly", then click on the 3 dots icon at top right, choose the tab with the drone icon, then disable Beginner mode.
Should you fly indoors, please note Spark only have sensor at the front. Put on the prop guards is advisable for indoor.
