Unable to connect LED Bulb to Yeelight app

I wanted to enable LAN Mode (formerly Developer Mode) in my Yeelight LED Bulb. This option as I understand is still not available in Xiaomi Home App, so I installed the Yeelight App. However the light bulbs are not being discovered by Yeelight App, despite me resetting them a few times (the bulbs did the rapid color switching routine). Despite that I did manage to add them back to the Xiaomi App

Hi,Both the Mijia account and Yeelight account work together. Just add it there. You can upgrade the Yeelight app version to the latest and try again
