Ran in the same issue, this is poorly documented.

It just seems to take 1-2 days till your SIWA is active. Nothing you can do but wait.

Why?

Hello, we are developing a Bluetooth Low Energy device which can be paired with our app and trigger an http call in critical situations. Our device triggers these routines as long as the app is active but after terminating the app the BLE device no longer is able access the background BLE process. Is there a way to trigger an http call via BLE in emergency situations? Greetings and thanks in advance!

I fixed the old sample to work with the current session state instead of session.isAutoCaptureEnabled toggle Fixed Sample Hope that may help somebody.

We run in this error a couple of times now. The solution was always to wait a couple of days until it works again. It usually occurs when enabling the SIWA in the developer portal or changing its attributes. So my solution would be: grab a coffee visit some friends come back cheers
