Video freezes on upload and Hudl tech is helpless – Hudl Review

I have been trying to film games and upload them using Hudl app. I can sit in my classroom connected to WiFi and record large segments of video and they upload. I go out to the field and film without WiFi and when I come back to school to upload it always freezes. I have deleted and redownloaded the app, in the fall I did this for football with zero problems. After the last updates to the app it continually freezes. Unfortunately I use my schools tech and they won’t let us use iTunes on our laptop.
