How do we enable multiple assignees to Azure DevOps tasks? Or is there any feature to add followers to Azure DevOps tasks.
To my knowledge this feature (to add multiple owners/asignees to a work item) currently does not exist with Azure DevOps.
One way that you're team could accomplish this is by using tags (however this wouldn't be ideal).
Of course you could have each individual create their own tasks but would not be ideal as data would be duplicated (waste).
You can subscribe to a work item by 'following' it, where that individual would be notified via email when the work item is modified. Documentation here: https://docs.microsoft.com/en-us/azure/devops/boards/backlogs/add-work-items?view=azure-devops&tabs=browser
You could request that Microsoft add this feature to their roadmap at the link below: https://developercommunity.visualstudio.com/spaces/21/index.html
