Recently I've exported videos from Premiere Pro and if you play them from the start until the end, the audio is absolutely fine and in sync. However, if you skip a minute or so ahead, the audio is out of sync and sometimes stops working. I decided to airdrop the video to my phone but the issue was still there. However, when I stuck it on GDrive, it played absolutely fine even when skipping ahead. It only appears to affect new video exports while my old exported videos play absolutely fine.
