Frustrated T Blogger

So I download this app and just when things seem to be fine, after noticing I had to pay to unlock the rest of the features, thinking it’s just $3, no big deal, unlocked the features and just when I was about to have the video saved, it just freezes up on me. Nothing happening. No, “YOUR VIDEO IS BEING SAVED”, nothing just some blank white square. So I delete and reinstall the app, did the same thing again, smh. I’m not trippin about the $3 but the fact that $ could have went to something else.
