Timeline alert “Zigbee has been restored"

Today I suddenly got a notification on my timeline. Where it says: ““Zigbee has been restored. Zigbee devices may need to be turned off and on again before they can connect to Homey again””
What’s happening, I didn’t ask or activate this action.
Looks like my zigbee devices are still connected to Homey, but I’m at work so can’t test this.
But what happened??? Can you see what happen??

I think the only way to find out is send a diagnostics report to Athom https://support.homey.app/hc/en-us/
