Can't register Gateway - EUI is still in use

Aside: while awaiting the response from a PM to the team, you can still use the gateway, though you cannot see it in TTN Console. You can see its last status timestamp and counters at http://noc.thethingsnetwork.org:8085/api/v2/gateways/eui-58a0cbfffe800edb

{
   "timestamp":"2019-12-18T21:23:22.499520241Z",
   "uplink":"32",
   "downlink":"16",
   "location":{

   },
   "frequency_plan":"EU_863_870",

   "time":"1576704202499520241",

   "tx_in":16
}

You should also receive data in your applications just fine.

(When clicking that URL, some browsers tend to change it to use https, which won’t work. Right-clicking and opening in a new incognito window often works for me then.)
