scheduled builds never trigger in azure devops pipeline

Question

I have the following configuration in my open source project hosted on GitHub: https://github.com/wez/wezterm/blob/master/azure-pipelines.yml#L9

schedules:
- cron: "0 0 * * *"
  displayName: Daily build
  always: true
  branches:
    include:
- master

my azure org is https://dev.azure.com/wez0788/wezterm. My project is open source and using the free tier.

The schedule doesn't appear to have any effect; no scheduled build shows up in the list of builds.

The documentation for build triggers has a troubleshooting section that doesn't have any useful information on why a scheduled build wasn't scheduled. It's not even clear if the syntax is correct as there is no UI to indicate whether the pipeline has picked up the schedule. The config is sufficient that pushes to the repo and PRs do trigger successful builds.

This question sounds similar, but with the notable difference that I've never had a single scheduled build ever run, so it's not an intermittent problem: Azure DevOps build pipeline unreliable triggering by schedule

Someone else appears to be having the same problem and filed a GH issue over here, but since that was a doc issue tracker it got closed: https://github.com/MicrosoftDocs/vsts-docs/issues/4589

How can I get my scheduled build to actually run?

Try to Use the following just replace double quote " with the single quote '

schedules:
- cron: '0 0 * * *'
  displayName: Daily build
  branches:
    include:
    - master
  always: true
