Using Azure DevOps (VSTS), when I try add any extension that add build tasks, the extension is shown as "Installed" but the task list isn't updated with the new tasks. I found solutions only for the on premise version of TFS (the classic clear cache folder) but I suppose that I cannot do this in the cloud.
The last time I needed to add an extension was aprox. 1 month ago I had no problems.
For example:
The google play extension is installed but none of it's tasks is shown on the task list, but it still appear as "Installed"
And on the Extensions page the extension is in the list as expected:

Any sugestions on how to "force" the task list to update?
Update:
The problem is not with a parcular extension, another test with some random extension from the marketplace:
