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.
