Verizon never suggested wireless backhaul capabilities between E3200 and CR1000A/B.
If you think about it, logically why should they support such a feature? E3200 is triband 5GHz Low, High and 2.4GHz. CR1000A/B is triband 2.4GHz, 5GHz, and 6GHz. 2.4GHz is not a candidate for its slowness. 5GHz is the only viable band, then this leaves CR1000A/B only with 6GHz for connecting the client devices. There are still way fewer client devices support WiFi 6E or 7.
