ZHA + Conbee 2 frontend slider slow to apply final state of Lights

Hey folks, could you help me figure out this one, please? I have no idea what is happening :face_with_raised_eyebrow:

Issue: Light slider have a delay on displaying final state of brightness percentage after it is updated, using ZHA and Conbee II.

TLDR:

Everything is updated. The light response is nearly instantaneous for Groups, Britghtness, Color change etc… Only the slider is delayed. The slider is custom but happens the same on light card. It happens to both Hue bulbs and Ikea bulbs/drivers connected to Conbee II being controlled via ZHA. It does not happen when the lights are integrated via Hue Hub or Ikea Gateway. Issue is present on every device I can load the Dashboard. Conbee II is updated to 26700700. HA running on PI4 via Ethernet. Other Zigbee devices are updating the state instantaneously too like Aqara door sensor. The light group is created via ZHA/ConbeeII not Home Assistant Group and there are no delays on the lights itself. Not sure if it is related but I also tried;

  customize_domain:
    light:
      assumed_state: true

and also false, neither made any changes.

Any help with be much appreciated :smiley:
