Snapchat video/audio out of sync?

When I record a video, back or front camera, there s no audio for the first 2-3 seconds of the video, then the audio starts like normal, so it looks like the video is sped up when it s not. I recorded on instagram stories and my normal camera, they are all in sync and perfectly fine, so I don t know what s the issue. I tried reinstalling the app, clearing cache and data, and even factory resetting my phone. I also disabled and enabled again the microphone and camera for snapchat. I don t know the issue.
