SimpliSafe shows no devices/entities

A couple of days back, all my SimpliSafe devices/entities magically turned “Unavailable”.

After long back & forth & frustration, I deleted the integration and re-added it. No error/warning, reading out the API key via developer toolbar worked flawlessly.

However, now the integration is totally empty – no devices, no entities. Looks like this:

Maybe the same reason that they became unavailable.

Did this integration get broken?
Anyone faced similar issues?
