No way to update firmware for Razer Kiyo Pro

HI, I want to update my Razer Kiyo Pro firmware to fix auto-focus issues. Originally, I was able to view my camera in Synapse 3 and change some settings, and I was told that new firmware was available. I clicked the URL to download the new firmware, and the website was broken. No firmware to download. I then tried to revisit my camera's settings in Synapse 3, and the Synapse 3 software reports that my camera is not plugged in. I've experienced multiple issues like this since owning the camera, like incompatibility with any of my USB 3.0 hubs. I've also experienced multiple issues with this camera on multiple computers, including two different Windows PCs and a MacBook Pro. While this is a high-quality camera, the software has consistently proven to be problematic. Anyone who wishes to purchase this camera should know that it is not plug-and-play. It takes real work to make this camera work properly, and even then, it will fail you sometimes. This is a software issue; not a hardware issue.
