We have a problem with changing end dates. I will explain this situations with examples. We have 2 type of problem but mainly same.
1-I have an open Issue and has an end date, for ex. 15.01.2020. Also this issue is "in progress" as an issue status. When I changed issue status to "to do" or any type of status , end date changing independently to 14.01.2020.
Also when you are changing end or start date on issue, date is going to 1 day earlier. For ex. I want to update start or end date to 15.01.2020. When click ok button and confirmed it for changing dates, issue updating date is going to 14.01.2020.
