We are currently having issues with OTAs/updates and are already working on them. We will release an update within the next few weeks that will resolve the issues.
With a BRAIN OTA, the BRAIN always restarts and therefore loses the connection to the app. We therefore always recommend restarting the app. After some time, the BRAIN should be displayed there again.
After a NODE OTA, the system can simply be restarted via the app.
