My best guess is that the %YourName variable is not getting set to present since that’s one of the main checks before the Tasker profiles if they should try to set you as away or not. My focus would be on trying to figure out why that isn’t happening.
Edit: You should be able to check the current status of the %YourName variable from the Vars tab of Tasker.
Did you see the “YourName Variable Set” profile getting triggered in your Tasker logs? You should be able to see it in the logs, but as a debugging step you could add an Alert > Notify with a title of %st_attr_value in the “YourName Variable Set” profile – then anytime your presence sensor changes, you should get a notification showing the status of the presence sensor if the push notifications are working as expected.
You can manually run the Depart and Arrive profiles to trigger this and see if it’s working as expected.
Can you open SharpTools, open the left navigation and choose Subscriptions, then tap the refresh button at the top and let the list of subscriptions refresh, then post a screenshot of your Subscriptions screen from SharpTools?
Either works, description is quicker and easier to read through, but the XML can be imported and tested on another device.
