Hi @ramonlsouza ,

I see how this can avoid the problem right now but it does not solve the bigger issue that is having the poll tag at the chat's message content. This should be at least associated with a new issue to tackle all the changes this feature need to be production ready.

Thanks for the review @daminebenq

Looks like another PR related to polls was approved before mine, and changed the way polls work on the back-end...

I'm fixing this and will send a new commit soon
