QS-Zigbee-ECC02 wall switch button response delay

Hi everyone,
I’ve got a Tuya “Mini Zigbee Curtain Module” (model: QS-Zigbee-ECC02), and I’m facing a really anoying issue. First of all, I want to add that my wall switch has two buttons, both with STOP function, and my device, and my ZigBee gateway also, both have the lates firmware version.

When I press my wall switch buttons, it takes 2-3 seconds to start opening/closing my curtain. The STOP function it as a delay of 0.5 sec.

In my SmartLife APP, whe “Switch Type 1” option value is “Button” (like it must be in my case).
If I change that value to “flip” it’s a mess becaus it flips my wall switch buttons action (the opening button sometimes closes it, and my closing button sometimes opens it).

So please, could you implement a new firmware version to fix this really anoying issue?
