Looks like they’re aware of the issue now...
There is a service bulletin on TOPIx that came up this month about a temperature mis-calibration from the factory. They have a temporary work around listed later in this bulletin (loading an old calibration file), but it’s not a fix.
My I-Pace (2020 June delivery) can be reset with the double pedal procedure and will show over 250mi of range for a few days, then it will reset to 201mi max as described in this bulletin.

Symptom 000101 Diagnostic Concerns
During PDI the retailer may experience range less than expected at 100% charge, specifically this has been reported as 325km or 201 miles which does not meet customers' expectations.
Affected Vehicle VIN Range
SADHA2B10L1F79241 – onwards
An erroneous significant negative temperature value (-40deg) is reported by the PCM during the vehicle manufacturing process (due to ambient temperature sensor not being fitted when PCM is first powered). This causes the climate system to send a very high predicted electrical load to the PCM (~5kW vs a more typical 0.5kW).
The PCM uses this load prediction to calculate a negative offset to the predicted range which is then stored in memory to avoid range changes between drive cycles. Any changes to this offset are heavily filtered and, as such, the range will be incorrectly reduced below the expected figure for approximately the first 11 hours of driving.
A range reset will not cure this as the climatic load offset is not cleared during this procedure (only the historic energy consumption is reset).
