Wyze Plug keeps changing MAC address?

As the title says, one of my Plugs keeps changing its MAC address, resulting in it going “offline” in the Wyze app and in Alexa’s Routines.

Over the last 3 days it’s had 3 different MAC addresses:

2C:AA:8E:66:AD:0A - Yesterday’s MAC (2020-10-27)
2C:AA:8E:78:84:7C - Today’s MAC (2020-10-28)

The only way I can get it working again is by removing it, resetting it, and then re-adding it to the App, which ends up showing the new MAC address.

Is the plug bad? Or am I going insane?
