Hi Tapo Community & Support Team,

I'm experiencing a persistent issue with my Tapo P115 smart plug that I cannot resolve despite multiple troubleshooting attempts. I would appreciate any help.

DEVICE & SETUP
Device: Tapo P115 Smart Plug
Phone: Samsung Galaxy Note20 Ultra 5G
App: Tapo (latest version)
OS: Android

WHAT HAPPENED
I removed the P115 from one Tapo account and tried to register it on a different Tapo account. Since then, I am unable to complete the setup. The Tapo app shows the error: "This Tapo device could not be found."

LED STATUS
The LED is blinking alternately blue and pink, which according to the app is the pairing/setup mode. However, the app still cannot find the device.

WHAT I HAVE ALREADY TRIED

Factory Reset (multiple times)
   - Held the reset button for 5–10 seconds while the device was powered on
   - LED blinked to confirm reset
   - Device restarts into blue/pink blinking mode (pairing mode)
   - Problem persists after every reset

Connected phone manually to the Tapo hotspot
   - Phone successfully connected to "TapoPlug7663" via Wi-Fi settings
   - Browser confirmed connection: navigating to 192.168.0.1 returned "200 OK"
   - Despite this, the Tapo app still shows "Device Not Found"

Disabled mobile data (5G) completely
   - Turned off mobile data to force all traffic through the Tapo Wi-Fi hotspot
   - Issue remained unchanged

Disabled VPN and all VPN-based apps

Moved phone physically close to the device

Closed and restarted the Tapo app completely

Tried the "Add Device" flow both via automatic scan and manual device selection (P115)

ADDITIONAL OBSERVATIONS
The phone is clearly communicating with the plug (200 OK on 192.168.0.1 confirms this)
The Tapo app however does not recognize the device during the setup process
I suspect the device may still be linked to the previous account on TP-Link's servers, even after the physical reset

MY QUESTION
Is there a way to fully deregister the device from TP-Link's backend so it can be freshly registered to a new account? Or is there another step I am missing?

Any help is greatly appreciated. Thank you!
