I am trying to create a poll to complete this challenge. But, the Ask tab is read-only. It is not allowed me to post the Poll on Chatter. 

How can I resolve this issue? 

Thank you! 

Hey There, 

I'm encountering an error with the polls. Here's what I've got: 

"Challenge Not yet complete... here's what's wrong: Could not find a poll with the specified options. Ensure you copy and paste the option text carefully."

I double checked the instructions and text that I put into the poll. Can someone please let me know what I can do to fix this? See the screenshots

for reference...

I'm trying to complete the chatter section on Trailhead, and I'm getting the error "Challenge Not yet complete... here's what's wrong: 
No feed post was found that linked to the Trailhead URL.", and this doesn't make sense because I clearly posted the URL multiple times.

The criteria: Using the standard poll and link Chatter actions, create two posts to engage with the Chatter user community.
Create a poll post. Ask your users to rate their experience with Chatter and ask for feedback in comments.
Create a link post. Share a link with other users to http://developer.salesforce.com/trailhead - the best learning tool for Salesforce out there!
