Hi @Kr1491 — good news and a small ask.

Your PR passed review in our backlog cleanup and was queued to merge. We merged 38 PRs today, and yours now conflicts with main purely because of that — several of them touched the same files. Nothing is wrong with your change.

To land it:

git fetch origin
git rebase origin/main
# resolve conflicts
git push --force-with-lease

Ping me here once it's green and I'll merge it straight away — it's already approved on our side, so it won't go back into the queue. Thanks for your patience with how long this sat 🙏

merge conflicts resolved, please check once, thank you
