Hi,
For several months now Virb Mobile and Virb edit are unable to export videos to YouTube.
Google has modifiied the way third parties are signing in with new security guidance. Garmin has not updated it apps. Thus it is impossible to export to an YouTube account because it is impossible to sign in (VIRBZ being consider by Google an untrusted app).
For those who expected to share on their account a video 360 from Virb 360, they just can . After 6 months now, Garmin have not bother updating its apps .
