Is it officially NOT SUPPORTED to use ESP-NOW and Wi-Fi?

There are two ESP8266's: E1 and E2. Both E1 and E2 are set to WIFI_STA, ESP_NOW_ROLE_COMBO for bi-directional ESP-NOW messaging. Additionally, Adafruit MQTT is enabled on E1. The problem is that when I enable MQTT on E1, ESP-NOW randomly fails. Both E1/E2 are set to use channel 1, and the Wi-Fi AP that E1 is connected to access the Internet is also set to use channel 1. But ESP-NOW mostly fails and sometimes succeeds.

So, my question is, is it officially not supported to use the Internet and ESP-NOW on the same ESP8266, and the times that it randomly worked were just a fluke?
