Polls

Hello guys,i I have tried several times to create surveys, but none of them went beyond the ‘pending’ status.
What is the reason for this?

(The polls were about tanks in the IDF tree, the AC-130 in the USAF tech tree and camouflage nets for tanks - so nothing special really …)

In addition, I have only ever been able to set a single question in surveys, although I have seen often enough that it is possible to ask a diverse number of questions in a survey.
I always get an error message …

Can anyone help me with this?
Thanks already
