When inputting a value with the Numeric Input widget using the pop up keypad on the iPhone (not using the ± step buttons) the BLYNK_WRITE function on the ESP device is called on every key press on the pop up keypad rather than when the ‘DONE’ button is pressed.
This was not a problem in November 2018 when the device was initially installed. The iPhone App & Blynk library were the current ones at that time.
I have tested the original sketch with Blynk libraries 0.5.3 & 0.5.4 but using the current iPhone Blynk APP and issue remains.
Not sure whether this is an APP or server issue and can’t test with Android or older versions of the iPhone APP.
