I think we'll probably need to inspect your logs to dig in and see what's going on. Can you get in touch with Client Care so we can open a support ticket? Thank you for your patience.

Have you tried on multiple devices/simulators? Or you can delete the app and install again and it will get a fresh ECID and push token. Just wondering if this is happening for only one ECID or all tests performed in this org?

From what I'm seeing, the push token isn't getting saved in the edge profile. It would be interesting to confirm that the info isn't making it there. If you wanted to verify that: head over to the profile view in Platform: https://experience.adobe.com/#platform/profile/overviewunder browse search us...
