Yeah, I saw that and dug in the settings to see if I could remove it but no luck after 2 mins of searching. 🔍 🤷‍♂️
Thank you for opening this issue. Linked to dwyl/learn-travis#67 👍

I think I found why Travis was required: https://travis-ci.community/t/known-issue-travis-ci-reports-expected-waiting-for-status-to-be-reported-on-the-github-status-api-but-the-status-never-arrives/1154

I've removed the Travis rules for the branches, let see if this fix the issue. The PRs have updated and Travis is now removed
