Audio no longer recording during tiktok screen recording. I've tried several screen recording apps (android).

I've been screen recording tiktok for about a year. Mostly I do it while I'm scrolling through livestreams.....because I never know what kind of hilarity/craziness/etc I might be witnessing.

But in the last few days, Tiktok's audio does not record through my screen recording apps........but gets recorded perfectly using every other app.

Any ideas as to what's wrong?

Thank you!
