Tiktok Not Completely Closing from Phone?

For those of you who use TikTok, lately I've noticed that when swiping out of it or even completely logging out, that the app won't completely close out when I'm on my phone. Even after I've signed out, I still hear talking from whatever the last user's account I was just on. Sometimes, I hear multiple user's account talking over each other.  Has anybody else noticed this when using Tiktok?

Needless to say, because of that, I've currently deactivated my TikTok account and have currently uninstalled it from my phone. Something seems off with not being able to completely log out of it - it makes me leery keeping the app on my phone (I don't think I will miss the app all that much, I've noticed I've been logging into it less and less anyway.

EDIT:  I've learned why the above was happening. Apparently, if you scroll through multiple videos before completely watching one video, it's not all that uncommon for videos to "run over" each other. The fixes are to 1) completely watch one video before scrolling to another one and 2) clear the cache. Interestingly, while those fixes work on the phone, they don't seem to work when just logging into Tiktok on the computer.
