Hello Folks,

When receiving the "Credential Status" email from Salesforce (after going to https://t.co/xfXDlCbX1f) for some reason (?) my Trailhead Profile appears as "not linked" (blank):
Here is a screenshot of the portion of the received email:

What do you think the reason is?
Salesforce has set a deadline to resolve this: 14th-Decembre-2018
Any clue?

My Webassessor seems to be linked already (as displayed above on the screenshot).

I can see that my Trailhead settings show my linked account as "inactive" (?) - I do not know what that means.

I have tried clicking the button "connect or merge" and I have re-provided my login credentials for my users but it says "Whoops, looks like there was a problem. Account already linked to this profile."

How can I resolve this? (Salesforce Trailhead Support has not replied my Case#00028586 which I created on the 14th November!)

Thank you very much.

Unable to install Data Quality Analysis Dashboards app from AppExchange to complete Trailhead challenge.  After reviewing instruction and troubleshooting videos, I still get the error.  I verified that the username was the one for my Trailhead Playground. I have used the link to the AppExchange app from the challenge, as well as going to the AppEchange dropdown from the Trailhead. I get to the install in production step and then the error occurs.
This app can't be installed.
There are problems that prevent this package from being installed.

Today I registered for a Trailhead account, and was doing file answering quiz (in English) until time came to launch Playground.
Once playground launches, it does so in Japanese I believe, though it could be Chinese as well. Not sure.
I can't figure out how to change the language either. Checked my user settings, email user settings, to no avail. Did search web for answer, which almost always point to a dropdown at the bottom of page to select your language. But playground doesn't have any dropdown.
Any help in getting English back is much appreciated.
Thanks In Advance.

Hello all,

I have been a serious user of SF for the past 9 years (partly as admin but mainly as business analyst). Now I am joining the trailhead community for serious learning (primarily admin).

I wanted to know whether I should start my journey with my official mail or my personal gmail. I don't want to lose badges and points etc; but will not using official mail restrict some functionalities?

Gratitude in advance.
