Hi Denis, always around to support, many thanks!
I think the settings are ok here, but I have narrowed the issue further: this mis-behaviour is only seen for answers that are not "manually" competed: in that survey, if you answer "NO" to the 4th question than none of the other questions show up and the survey takes you to the "post completion" message "Thank you blablabla..."
In that case, impossible to come back to the survey and edit it
If the answer is fully completed manually - then the survey allows me back in for edits...
There is an easy way around I guess, by simply adding one last question (probably a text display too) which will show up also when answer to question 4 is NO, so that then the user manually presses "Submit". However I wanted to point that out in case you would want to investigate further the issue,
Thanks!
