Actually the issue was of date format in Android the supported format is "YYYY-MM-DD" So it might work for you as well
or if you can show me what you have done then it'll be informative & understandable!

check out if dateString : new Date().toLocaleString() may make mistack or try this current={"2020-11-27"}
current={"2020-11-5"} may make mistack should be "2020-11-05"

In my case, the issue was from the current date format,
I use and works fine for me
current={moment().toISOString()}
