Hello Friends!  
Using self -hosted Mender 3.4 I encountered a bug in the WebUI.  
My device is preauthorized and added to group via API call. After some time the device is available in the UI. When I move the device to a new group and than back to the old or a new group, then I see the message `accepted devices couldn't be loaded. timeout of 10000ms exceeded` and the UI hangs in some kind of update loop. The page is then no longer responsive. RAM usage goes slowly up and at some point my laptop is crashing. I can only close the page and reopen it.
