That is quite possible as typical Wyze use is to view a camera and then press the home button on the phone to exit, however, applications should not be maintaining control of the mic (what appears to be the issue) as a background process when they are not open.
This seems like a serious security vulnerability since a breech could mean access to spying on people through their mics that remain open even without the app open. After all, we just had a security scare with Wyze releasing our information to the dark web thanks to the latest breech.
In any case, the public needs to be made aware that normal Wyze use is likely to cause problems with bluetooth devices, such as in their vehicle (which almost every car has these days). It certainly would have influenced my decision to purchase the product.
