Azure repos are kinda fine. It's really basic and there is nothing to break. I actually really really like their ticketing thingy for the same reason. It has the necessary stuff and the management types can't add a million of fields to it and annoy me with reporting, burndown charts or what not.
It has an annoying bug where approving PR's from the cli won't delete branches when you squash commit, while clicking the button in the UI does it perfectly fine. It's been a bug for a while (as in several years), and if you find something like that, don't expect it to ever be fixed. As a whole it's not a bad tool though.
As you say it's limited, but that can be both good and bad.
Yea, I have Azure DevOps with free action minutes and I’ve started using it a ton more since it avoids all GH outages.
