Does anyone who works in Android dev know what's going on with the app TikTok itself?

It's so bug-ridden but each update introduces new weird behaviors and each is so unique and could change at any point it's almost strangely satisfying when you succeed in working around them to get your intended results.

The app weighs in (for me) at over 13gb, after cache clears in app and os. Some of it just seems like bad coding but all that is beyond me
