I have a plan based on 6 teams' boards plus a program board as issue sources. I noticed that completed releases do not show any issues in the reports even though the issues seem to match the board filters. So I tried to run through the plan setup wizard again, but in going from step 2 to 3 I get the "Bummer, something has gone terribly wrong ..." error.
Anyone know of some basic things to check before filing a bug report?
