Hi,

The link "http://preview.d2l.ai/d2l-en/PR-1982/" just forwards me to the d2l.ai home page. I'm not able to view any build results.

Please let me know if the PR needs to be created on a branch different than the "release" one. The master branch doesn't have as many pages as the release one and is way behind it when comes to commits.

Thanks. Can you send your PR to r0.17 branch?
