We updated our mender from version 3.6 (to 3.7) to 4.0. The devices are connected and send data, but in the overview, they are shown as offline. One device in the screenshot below has a “Last check-in” timestamp which is just a few seconds prior to the screenshot, but still is shown offline.
Is this something which has to be configured in Mender 4.0 or is this a UI bug?
