Teckin/Tuya SP25 Plug: Successful Flash, Successful Wifi setup, dead after post-wifi-reboot

Hello,

Odd issue. I successfully flashed the Teckin(Tuya?) SP25 smart plug. I used the latest `tasmota-lite.bin` as advised in the readme.md. It succeeded just fine. I was able to connect to the devices broadcasted wifi and it saw my home wifi, so I clicked it and entered the password (Yes, I reconfirmed it multiple times before saving it). It reported something about successfully connecting and stated it was rebooting.
It never (from what I can tell) powered back up. So I unplugged it, held the power button while unpowered, to drain any charge in the caps, then plugged it back in. The light turned on for a flash immediately after insertion, then back off immediately, and nothing.
I checked my gateway for its MAC as a wifi client and it isn't listed, so I think its clear it is actually not powered on.
I plugged a device into its USB output to see if it was relaying power by default, and no
I plugged a device into its standard outlet (3prong power), and also nothing

So odd, since it took the firmware just fine and ran the wifi setup and everything. Am I missing something obvious here?

EDIT:
After reading some troubleshooting info (https://tasmota.github.io/docs/Device-Recovery/#fast-power-cycle-device-recovery), I reset the device with the re-insert-power-6-times method, which put it back into config mode and I could access it again to set up SSID/Password. I again clicked my home wifi in the list, and entered the password. It showed the below image then restarted.

As before, its MAC is not showing up in my gateways wifi clients.

EDIT:
In case it matters, this is the wifi settings on my gateway:

EDIT:
I'm a dumbass. I was looking for the wrong MAC in my wifi clients >.<
Its there. I'll go check/add the SP25 to the doc if its not already there

Start with readme.md and the linked Device Recovery documentation, then check whether the Teckin/Tuya SP25 is already listed in the device documentation. If it is missing, document the successful flashing and Wi-Fi setup details, including how to identify the device on the gateway; done means the SP25 entry is accurate and the reported recovery path is clear.
