HomeKit alarms broken with 2021.8.4?

Configuration
1

Hello all,

I use the HomeKit integration to expose my Simplisafe alarm integration to my Apple home. I ran the HomeAssistant 2021.8.4 last night and just noticed that my alarm control panel no longer is pushed to the Apple home app. It seems that my door sensors are still being pushed through, just not the control panel. I see the entity in the HomeKit integration and it’s checked that it should be exposed, just seems like something is broken. Is anyone else having issues with alarms and homekit after the latest update??
