问题
We currently have our Azure DevOps release setup in the following way:
What I'm trying to accomplish is to cancel the 2:00 PM deployment if the 9:00 AM deployment triggers, as well as cancel the 9:00 AM deployment if the 2:00 PM deployment triggers since we don't really want to deploy the same code twice, or even deploy the previous day's code the following day.
Does anyone know if a way to do this in Azure DevOps?
I've done a lot of searching for extensions, etc. to see if I can find anything, but so far have not been successful. Any help would be greatly appreciated.

Additionally, you may try to use Release Gates with Rest Api or Azure Functions. You can find example here: Azure DevOps release gates with Azure Functions, PowerShell and VS Code

Assuming you trigger the release at 9:00 AM. Then you can take the following steps to implement it:
1.Add a variable named flag and set it as true in the Variable Tab
2.Add a PowerShell Task to your Test Stage, Starting 9:00 AM Stage and Starting 2:00 PM Stage
(1) Add a powershell task at the end of your Test Stage to set the flag to true.
(2) Add a powershell task on the top of Starting 9:00 AM Stage to check if the variable flag is true, If flag is false then fail this task, Below script is for example.
$flag = “$(flag)”
if(-Not $flag)
{
exit 1
}
Add a powershell task at the end of Starting 9:00 AM Stage to set the flag to false, if this stage is deployed successfully.
Repeat above steps for 2:00 PM Stage.
