I was trying to fix an issue with my build pipeline in Dev Ops, but for some, reason all the tasks on all the pipelines have been removed. I get the error 'This task is no longer installed' on all tasks.
I have tried to revert the pipeline to the last good known configuration, with no success.
Also, I am unable to remove the task and reinstall them as they do not appear in the task list.
Any help is greatly appreciate as it is driving me insane!
UPDATE
Here is the setting for the Pool
