Hi,
I have start date and end date as two different date pickers,
Formula for start date

Formula for end date

I have to display these dates in one gallery, I have formula in items of gallery as DateRange

I have one button to patch all dates displayed in gallery to Sharepoint list. Formula to patch all dates in splist is
Here My issue is : If I select dates for two months(02-08-2021-02-11-2021) all dates are getting displayed in gallery but it is not getting patched, while patching some dates in between are missing when patching to splist from gallery. And also it is taking much time to patch when I select more dates.
Sometimes , all dates are getting patch , but in most cases only few dates are getting patched from gallery to splist .
Any suggestion would be helpful
Thanks in Advance
