NEO 1 FTMS Firmware Update??

#Tacx-Hilko. We need this update please to enable ERG mode on Xert IOS Player training platform. Xert Support advise 'For those that are using Tacx, most of their smart trainers support FTMS except for older Neo series that do not yet have it. Contact Tacx Support for firmware updates for your Neo as Tacx have have committed to providing support for these trainers'. Tacx have a lot of loyal Neo 1 customers please support us.  I remember back when the Neo 2 was announced Tacx promised updated firmware for both the 1 and 2 but still nothing.
