"Calibration failed"?

'Anyone else unable to/have difficulties calibrating their Mini 2?  I've tried several times over the last two days, clear sky, waving around like a "figure 8" as instructions say but no luck.  I didn't buy this device for its compass, but it's not reassuring that I can't get it to calibrate.

It's also strange that ever since my first failed attempt at calibrating, I can't even find the compass.  I remember seeing it before (in the Navigate menu maybe?), but now I can't even find it (?)
