Warning: zigbee2mqtt only supports architectures and/or machines which are no longer supported

After the HA update 2026.4 I get a repair notification:
app 81bc2df9_zigbee2mqtt only supports architectures and/or machines which are no longer supported by Home Assistant. It will stop working in a future release. Selecting Submit will uninstall this deprecated app.

Running HAOS on a Raspberry Pi 5. Zigbee2MQTT version 2.9.2.
Anyone any idea of what’s causing this message, and what to do to get it fixed?

Solution found for the moment: just wait and see the notification disappear by itself after about 10 minutes…

We’ve been holding our collective breaths for a day (bots too) and no updates?
