1st time i've used this app everything is ok. Then, after editing i save the video but when i want to continue editing, my video is freezing, cannot play and edit. The video is less than 16 minutes long. I 've wait for hours, still cannot play & edit. Lastly, i've to delete the edited video & do it again. This is suck...waste a lot of my time. Now its happened again, i don't know whats wrong, because no notification given by the app...please fix this asap.
