Multiple issues with Matter Light Bulb sample connecting to Apple Homekit

Hi,

I'm trying out the Matter: Light bulb example using an nrf52840 device on NRF52840-DK. So far, I have managed to build the software, flash the device, provision it into the network using Apple HomeKit at iOS 16.2

But I am facing the following issues

1. After setting a brightness of <100% if I switch off and then switch on I see the old brightness level is not preserved, it shoots up to 100% every time. I see that there are 2 requests coming to the device, 1 -> Turn on, 2 -> Set to 100%, but that's not the case with any other homekit bulbs

2. If I power off the device for more than 5 minutes, and then power on, the device doesn't work anymore, it says it's provisioned and connected from the log but still no response on HomeKit App. If I power off and power on immediately, I see  it's able to connect back to network and works.

3. When I first provision the board in homekit I can't identify the bulb with a blink from HomeKit app.

Are these known issues and in the process of fixing?
