We are aware of an issue where if you set a location, the explorer and mobile app shows “null, null, null”, “undefined, undefined” or “no location set”.
Rest assured the location has been recorded on the blockchain but the geocoder is not translating the latitude and longitude into a location.
The team will be investigating this issue today.
Until we come to a resolution, please avoid re-asserting your Hotspots.
If you want to double check that the change made it to the blockchain, you can check by visiting the api:
https://api.helium.io/v1/hotspots/<your hotspot address>
and look for the lng and lat values.
