After 12 hours of work I saved it up with a view to tweaking the mistakes that were in there.
Beforehand I exported to MP4 and it took a long time. finally producing a video of 24 minutes on a 4+ minutes piece of audio
Opening it the next day the issue started. If I play a few seconds of the video and stop it then restart at that point the video tracks fine but the audio starts from a much earlier time.
I updated to the latest version and the issue is still there. I tried a clean project and the issue is on that one also. Any advice is appreciated
