@ErikSchierboom I am no longer able to merge my own nor other contributors' PRs, do you know what's going on?

My understanding is that while a track isn't launched, no reviews are needed before merging. On a live track, PRs should be reviewed by someone with write access besides the submitter before merging. So if Erik changed the merge settings, that'd make sense as to why you can't merge your own. That's pretty odd that you can't merge other PRs. If that just started occurring, it might be related to the work staff did in the last day to give @exercism/cross-track-maintainers write access to most of the track repos.

I'm a member of that team so I can wave your PRs through as needed.

On a live track, PRs should be reviewed by someone with write access besides the submitter before merging.

Ok, makes sense. But just 2 days ago I was able to merge my own PRs, see #139 and #144 🤔 Maybe there were recent changes to the merge settings.

That's pretty odd that you can't merge other PRs.

Just tried it with #49 and was able to merge it only if I previously explicitly approved it. It might be faulty memory of mine, but I feel like I was able to merge other people's PRs without explicit approval.

Sounds about right if the staff weren't able to change those track settings before launch. So the issue at hand is that PR reviews are now required before merging, not that you can't merge a PR after a review was done, right? The former is expected behavior, but the latter might be indicative of a bug.

[0xNeshi]

Exactly. I've been in contact with Exercism support, and they explained they'd like all PRs to be reviewed by someone, even PRs from maintainers. The fact I was ever able to merge my own PRs on a live track was actually the problem 😅
