There is an issue with the date picker as you can see here:
1.The date I selected is not the one displayed
2. Impossible to change the time : if I type 1 it’s write 5 etc…
3. If multiple clicked on a date it’s change the time
On another note, this is clearly the worst customer support tool I ever experienced (small windows to write a message, error because someone has created a ticket with the same title, obligation to register to contact support etc…)
