Oh, right on. I remember that topic. I re-read it to bring myself back up to speed on this. 
Okay, so if the chime was wired correctly—the red wire from the transformer was connected to the TRANS terminal and the red wire from the doorbell was connected to the FRONT terminal—then it seems like you’ve connected the Chime Controller correctly according to the standard installation instructions. 
In that case, I’d be looking at app settings. Since I don’t have Duo Cam Doorbell, I wonder if your settings options are the same (or similar enough) as they are for Video Doorbell v2. Do you have an option like Settings ➜ Chime ➜ Doorbell Chime Type or something similar? For Video Doorbell v2, I can change Doorbell Chime Type to Digital or Mechanical, so I’ve chosen the latter. If you don’t see an option like that, then from the main Settings screen I’d do a Restart and then look again. The solution may be as easy as choosing the right option in Settings, and that may take some trial and error. You might consult the Video Doorbell v2 Troubleshooting article about chime problems for more detail, because there doesn’t seem to be an analogous article in the Duo Cam Doorbell Troubleshooting section of the Help Center.
Note that one of the steps in the Video Doorbell v2 Troubleshooting article suggests the alternate wiring instructions that I linked above, but I would personally hold off trying that until I got to the point where I thought I’d need a different transformer (i.e., I’d try other steps first, including testing the wiring to the FRONT and TRANS terminals [see below], then try the alternate wiring instructions, and then I’d consider a transformer upgrade as a final step).
If that doesn’t get the result you want, then I’d still wonder about the red FRONT and TRANS wires being switched before you started, so I’d probably use the multimeter to test like I described in the other topic. At least then you can reassure yourself that the chime box is wired correctly. (You might want to do this first, anyway.)
If that’s all correct but you’re still having performance issues, then this is when I’d consider a transformer replacement, since your 16 V AC / 10 VA transformer is on the low end of power output for what Wyze recommends.
I hope that this all makes sense and helps in some way! Feel free to respond here or in the other topic if you have follow-up questions, and please do let us know if you get this working the way you expect (and what ends up being the solution)!
