@Fae First I want to give you a huge THANK YOU for being so responsive and forthcoming with information. It's been such a relief. I do have another follow-up question for you: my OC300 controller version is 4.3.5, and the firmware is indicating 1.1.0 build 20210406 Rel.58776. Do you anticipate that I will be able to update directly to the latest patch when it is available?

@Fae As the firmware of controllers has been behind for quite a while compared to software version (5.0.29 on Windows and 4.4.6 for both OC200/300 firmware), when can we expect the latest patches?
