When I got to the office today and started to prepare for sprint planning I all of a sudden couldn't see Epics in the backlog. Pretty confusing because I can see them if I use the same filter in Jira.
After a while my colleague discovered this minimalistic arrow on the left side of the backlog and - behold - there they were. But now I can't work as I'm used to and the sprint planning is put on hold.
How can I protect myself from future surprises like this? And where can I find information about how I'm suppose to work with this new functionality?
