I have the same issue
This is the way it is with hass.io. The update icon is for Home-Assistant; not the HASS.io docker file. Hass.io updates are usually 24 hours behind home assistant ones. Just keep checking the Hass.io control panel and when the update is available, it will be there.
Want Tesla support now
Hope that hass.io will receive update at the same time in the future. So we not get false hopes a new update is ready
It is always good to wait 24h b4 updating anyway, just to make sure it is not pulled and see some feedback from others.
