We have just upgraded from 2.4.3 to 3.1 and have exactly the same problem.
You can't export the analysis page (which is lovely and we wish you could export this to excel), you can only export the responses to csv or excel. We really need to have both pages of the export back.
In addition we have a scale of 1-10 with (low) next to 1 and (high) next to 10 and the export only seems to export responses for those values, nothing in between, even though responses for 3 or 7 etc are shown on the analysis tab.
Is there any plan to fix this and bring back the two page export? Or is the Questionnaire plug-in a suitable alternative?
Thanks for your help
