Heh. When I first set them up about a year ago, it worked. It reverted to the system sound (even though android said app provided sound, and Wyze still showed Wyze Sound 1) at some point a few months later, I think after an app update. At that point I was only able to fix it by uninstalling and reinstalling the app.
Then a few months later it happened again, definitely after an app update, and this time I could not even fix it with uninstall/reinstall. Decided why waste time troubleshooting when I can just find a system sound to use (my hesitation was just that I was “used” to the wyze sound, but now I’m used to the system one). Has been flawless since.
Well almost flawless, it does still frequently send the my custom system sound 1.5 or 2 times (sometimes just 1). It also did that when the Wyze sound was working, and with the default system sound when it was doing that. Others have reported the same, but not a big deal. None of my other non-Wyze notifications ever send it more than once.
There used to be an issue that when you installed a new camera, all notifications started showing the wrong time (I think it was Pacific time, so they all showed a few hours off), which could only be fixed with uninstall and reinstall. I think that has been fixed, I haven’t noticed that in a long time and I did have to replace a camera a few months ago.
NOTE - do not uninstall the app if you are still on the 2.X version. That likely means your device is not compatible with 3.x and you can no longer do a new install of 2.X!!
