No-one out there who can help?
Sorry for the troubles. I have been unable to reproduce this issue.
1. Does this issue appear in the final export when saved to Device or YouTube?
2. If enabled, can you try turning off Cross Dissolves to see if that helps?
This happens when editing and in the rendered video regardless of whether cross-fade is enabled.
I have exactly the same issue. Not all the shots start with a freeze so it looks like a little bit random but most of them. Does not matter if I have crossfade enabled or not.
I have OnePlus 3T, Android 7.1.1
Very annoying, as this way the app cannot be used.
