Probably 2/3 of my day job is implementing Azure Devops for our internal and client applications - personally I really like it although it certainly has a learning curve and some things are non-intuitive. But everyone I've talked to who has used it in a professional context more than once (e.g. not tried it once and given up) is more-or-less very happy with the quality and reliability.

If you're good with Powershell it's also extremely easy to write your own build and/or release steps which is a huge plus.

For us, a few weeks ago Azure DevOps randomly stopped processing GitHub webhooks, so merge commits didn't trigger builds anymore (and we're not the only ones, see https://developercommunity.visualstudio.com/content/problem/...). A fix for this issue still isn't deployed.

Just a few days ago the service connection to Azure suddenly stopped working with "401 CouldNotFetchAccessTokenForAzureStatusCode" which appeared when deploying to Azure AppService. We had to recreate the service connection to get it working again.

Recently we also wanted to move our Android builds to Azure DevOps but in the end the documentation was so confusing that we just used Bitrise instead.

At work we are moving from VSTS to Jira :( sucks. It’s soooooo sloweeee compared to VSTS... luckily we can move our repos to GitHub.
