Sounds like a regular ZE40 to me (I've had my ZE40 Q90 for 5 years now). There is very little regen when you lift your foot off the accelerator pedal with them. You really have to apply the brake pedal to get the regen, especially as there is no 'B' mode like you get if the ZE50. To me the ZE40 does feel like a normal ICE car in that respect. Change the display so that you can see the kW being put back into the battery when you apply the brake.

 

As Zoe was one of the first mass produced EVs in Europe, they made the experience as close to a "normal" automatic as possible, so there is some regen when you lift off the throttle -not a lot (and then when very slow, it will creep forward).
Pressing the brake will balance re-gen and friction braking. Regen is slower to react than friction braking, so if you press the brake pedal swiftly you'll get some friction braking till regen is able to take over and if you brake hard then friction braking will be mainly working as you max out how much re-gen the car can do. It is also all friction braking at very low speeds.
There is a small window when the battery is full that it is friction braking only.

 

its a good thing as coasting is more economical than regen ( if you dont require mechanical braking).
Zoe also increases regen with light brake pedal pressing before engaging mechanical braking. so with good anticipation, you can average well over 4MpkWh with ease

Over 4mpkWh?! I drive with far too heavy a right foot to ever get over 4!
I usually get 3.8, and am well chuffed to ever get up to 4. But over? I'm going to have to drive like a granny!

 

Even with brake pressure I never found the Zoe 40 regenerated particularly 'effectively' (heh ... /sarc ... I mean not a lot of regen power).

The Ze50 was better, but that had imperceptible build quality, so was duly rejected.

 

I drive with the dashboard set to show power used/regenerated, it’s interesting to see how speed, and other parameters, affect regen. My ZE40 regens harder than an ICE on overrun.

 

@RiverRock nailed it. At very low speeds (say under 5 mph) the system can no longer regen, and the friction brakes take over. especially in damp weather, it's a noticeable transition.

Shameless self plug: If you get CanZE, the app will show not only how much brake torque you are requesting as a bar, but underneath it a thin blue bar indicating how much torque you can apply without the need for friction braking. The latter is indeed a function of state of charge, and battery temperature.
