In ShiftCare App you are unable to view next months shifts on one page. This is because last week of the month only shows shifts till the end of the month (not the whole week).
In an example below, staff cannot view shifts till Friday on this screen as 31st July is the last day of the month.
In order to view next week shifts, staff needs to click on the bar on top of shifts.
Clicking on this bar will open below page. Now click on the any day of first week of next month. In below example its Aug 2018.
This will open next months roster for you.
