Good afternoon.
I have JIra v8.21.1 and BigPicture Enterprise v8.5.2.
Some users do not see columns and there is no way to configure them on the Gantt chart. There is a similar query Column disappeared in the Big Picture program (atlassian.com) But I have a newer version.
There is no button for setting the selection of a set of columns.
But it's in the config settings.
Maybe someone knows the solution to the problem?
