Yes it happens on all clips both recorded before and after the update. I’ve restarted the app, and signed out and back in. Also tried in portrait and landscape mode.
To be clear:
Before this update using the slider to ‘scrub’ through the video updated the video in real time with the scrubber. Sort of an awesome fast forward/rewind.
After the update the slider just updates the numeric video position but not the video itself. When you release the slider it jumps to the new position correctly
