I posted the required link from my phone which I'd connected to one of my trailhead playgrounds and then I check the challenge and it says "Challenge Not yet complete... here's what's wrong:
Could not find a link post to Trailhead in your Chatter feed. Please check the requirements."
However, I can see the posting. How can I complete this challenge to get the badge and points?
Challenge Not yet complete... here's what's wrong: No feed post was found that linked to the Trailhead URL.
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!
