Alexa Devices Illuminance & Motion Sensors

I recently installed the Alexa Devices integration as I wanted to use the Illuminance & Motion Sensors in automations but the two sensors go unavailable every few minutes, even though the device is showing as remaining online.

I looked around online and this was a known issue a couple of weeks ago but is now supposedly resolved. Everything is up to date and I have tried reinstalling the integration without any success.

Just wondering if anyone else is still having these issues or if I’m missing something?
