M5UI / missing feature: You cannot set the screen brightness (hardware) - but in M5GFX you can.
MQTT / connection issues: MQTT loses its connection every 30 seconds or so. I have to check the status in the main loop and force to reconnect every time - which also takes some seconds. The same application runs on M5Stack Core2 (UIFlow 1) without any interruptions or issues.
