Hangs on "Focusing..." in any case, and crashes.

[Riodinino]

Hi,
I installed the app on my Sony Rx10 m3 today, and tested it immediatly. I could adequately set the min and max focusing distance, and choose the number of points, but turns out that right after, the apps hangs on the "Focusing" message without much happening, long enough for the camera to crash or go to sleep-ish mode (I ignore if that's it, whatever, when pressing any button, the camera restarts as if I just restarted it). Has this problem been reported, and is there any simple solution to it ?

Best regards,

Nino
