ActivityTransitionUpdate returns null, always. But if I change it to requestactivityupdate it works fine. But I need the transition API. I do not understand why this is not working, especially since a couple of days ago it was working right.
I have tried rewriting the code, looked everywhere on the web, copied code from other projects that apparently work, but the requestActivityTransitionUpdates does not want to work anymore. I have also uninstalled and reinstalled android studio, but nothing is working.

I expect to and was receiving transition updates when the app was open that were being stored in a csv file in the apps cache. Now my OnHandleIntent is not even being run from the task as it should be.
