When I select the time first in the date time field it does not hold the value and when I do the same again and select the time first it holds it. Below is my code : JS : @api endDateTime = null; handleEndChange (event) { this.endDateTime = event.detail.value; } html : <lightning-input class="" type="datetime" name="End" label="End" value={endDateTime} onchange={handleEndChange} message-when-value-missing=" " message-when-bad-input=" " required></lightning-input> [![enter image description here][1]][1] [![enter image description here][2]][2] [1]: https://i.sstatic.net/zKUBE.png [2]: https://i.sstatic.net/rF0hs.png
