ZHA OTA does not seems to work anymore

[musicscore (Paul)]

Looks like ZHA OTA updates does not seems te work anymore.
I checked the forum and what I could find is that the ZHA OTA update config changed.

This is the config I now use :

zha:
  zigpy_config:
    ota:
      # Disable all default providers, just support this one
      providers:
        - type: ikea
        - type: LEDVANCE/OSRAM
        - type: Inovelli

But still not working.

Below my old config that worked in the past but is not working anymore (it seems ) :

zha:
  zigpy_config:
    ota:
      ikea_provider: true                        # Auto update Trådfri devices
      ledvance_provider: true                # Auto update LEDVANCE/OSRAM devices
      salus_provider: true                      # Auto update SALUS/Computime devices
      inovelli_provider: true                   # Auto update INOVELLI devices
      thirdreality_provider: true             # Auto update 3REALITY devices
      otau_directory: /config/zb_ota_auto_update # Use .ota files to update others

All devices are saying : Firmware - Unknown :

Home Assistant version :

Please help.

I also see the same behaviour, i have lots of Ikea devices and all of them says firmware unknown. Even devices that has previously been updated with ZHA.
I used to think this was specific to Ikea products but just today i discovered something that leads me to think this is something more generel with ZHA.
I have 3 Sonoff temperature sensors, SNZB-02P. I bought them as a 3-pack.
Today, ZHA suddenly found a firmware update for one of them, it downloaded and installed fine. My other sensor, identical, however still says Firmware Unkown many hours after updateing the first one.
How can ZHA find a firmware update for one of them but not for another one?
