Callsign Alaska 120.
Around 14:48 I was holding at runway 27 at Yakima Air Terminal (KYKM), takeoff was requested and then suddenly the app froze and lagged and took me to my home screen. when I reopened the app I was still at the runway with a message ‘please expedite’ ; I’m unsure whether this was to takeoff (as I don’t know if my request sent) and so I [stupidly] proceeded to takeoff and was reported as I rotated. I did however check the ATC log but couldn’t then see whether I was cleared.
I’m aware that I did make a mistake, and should probably reset my device due to playing easier.
However, I thought I’d reach out to see if there was any chance of a report repealing. If not, it’s fine and don’t worry and sorry to disturb.
