LM3880: Questions about EN

Part Number: LM3880

When setting the EN terminal of the LM3880 by the resistance voltage divider method, the resistance voltage divider diagram on P6 of the data sheet shows input supply 2.7V to 5.5V, but considering VEN: min (1.0V) max (1.4V) If the power supply voltage is not 3.78V or higher, there is a possibility that some ICs will not start due to variations in the IC. What about?

In addition, the method of connecting the capacitor is also described, but in this case it seems that it does not violate the prohibited items in the case of cold start.
In the case of a momentary power failure, is it possible that the charge charged in the capacitor remains and violates the prohibition?
