Arwen 450C YLXD013-B not reacting properly

Hello YeeLight Community,

the 450C YLXD013-B light has serious problems.
The Bluetooth remote is mostly not working, sometimes after reboot.
The app is slow and hanging.

MI ID: 6282732358

My YLXD12YL light is working perfectly every time.

Blocking network connection keep the Bluetooth remote alive and controlling the light locale with home assistant keeps the connection. But I think that is not what I paid for.

How can fix the issue, that the remote stoops working after time?

@morgan Can a stuff member response to the issue?
