@Hank21 yes, I listed the issue in my inital post.

  @Hank21 Speaking of 610v2 firmware and issues.  Now that the 650/670 have a PPSK firmware, can the 610v2 get updated to add PPSK that it is supposed to have?

  @Hank21 I have the same question, but for different reasons. The EAP610 does not support AI WLAN optimization, whereas my other EAP615-Wall APs do. I'd like to automatically optimize my setup to improve seamless roaming. Thanks

I ended up returning the EAP610 as I found the firmware far too buggy. I did attempt to work with TP-Link engineering, but don't feel we got anywhere of value. The beta firmware that was provided caused the device to stop broadcasting any networks. This required me to factory reset the device and readopt. After the update IoT devices still could not join the network unless wireless security was either remove or used, but with only lowercase letters. TP-Link did attempt to shift blame to the IoT devices, but I find this hard to believe when they're made by different manufactures and connected to an EAP245 V3 and an AT&T ISP wireless modem without an issue. I left Ubiquiti due to the frequent bugs in firmware, but didn't expect to go nearly a year between firmware updates.
