I am working on an ipad Pro.
A few months ago I puchased a tutorial consisting of 11 seperate videos which required me to use Dropbox to download them. All these videos worked perfectly at first.
Now, 3 months later, every video on opening begins playing correctly then after about 45 - 60 seconds the picture freezes, the voiceover is silent but the timer continues to roll as though the video is still playing.
Please can someone be kind enough to help me solve this problem.
Many thanks
