iPhone 17 video audio

Hey guys, I recently got an iPhone 17 and I'm having a weird issue when recording videos directly inside the Facebook Messenger app.

Sometimes the audio is completely fine, but other times it sounds super muffled, almost like I'm underwater or the mic is completely covered (it’s definitely not). It seems totally random.

Is this a known iOS bug or a Messenger optimization issue? Has anyone else dealt with this, and how do you guys fix it? Thanks!
