Copilot no longer responding the comments on PR. This was working fine until about 18 hours ago, roughly midnight UTC time. Now when I @copilot in a comment on a PR it no longer picks up the comment. Also, submitting a Requested Changes on the PR doesn't work anymore for Copilot.

I've been using this since day 1 and never had any issues until now. Did something change? Feels like a bug to me. Anyone else having this issue?

I am having the same issue on my enterprise account from a different computer, repro, everything. Seems like this is a widespread issue

Seems to be working now on my personal and work accounts. Not sure if it's fixed, or I just got lucky

In case it helps anyone, GitHub "improved" the PR experience:

"In response to user feedback, we’ve updated Copilot so it will only respond and make changes when explicitly mentioned with @copilot in a comment by someone with write access to the repository.

This means that:

You can leave notes and thoughts in pull request comments without Copilot interpreting them as commands.
Others can leave feedback on Copilot’s pull request, but you get the final say on what changes are implemented.

"

I tried tagging copilot in multiple places without success...

having the same issue.

examples:
JohnDeved/pokemon-save-web#20 (review)
butterflysky/butterfly_bots#3 (comment)

it used to react with "👀" and then start work on the requested changes or comments.
this seems to be broken right now and Copilot does not respond anymore or react anymore.

Yep, exactly the same here.

Tagging copilot doesn't help, he still ignores comments.

[JohnDeved]

for me tagging copilot works

You need to make a NEW comment with copilot tagged. Editing an existing comment doesn't work.

Would have been nice to announce this wider than a blog post...

Tagging Copilot also works for me. It is not enough to write Copilot, you have to use @copilot

This is really important information that I don't feel has been clearly described anywhere. but it worked for me, so thanks for all the help. it should be pointed out somewhere
