Joining to Helium was always a hit-and-miss process (since SX12xx times), however, provisioning the WM1110/BasicsModemSDK device through Helium console succeeds after some attempts (usually the device struggles to recognize the JOIN_ACCEPT message).
By provisioning the same device through the Locator instead, joining is almost impossible, although it did succeed once. What is your experience connecting to the Locator through Helium? Any tips? Seems like a downlink communication problem, at least for EU868, and in this case geolocation services relying on assistance data will be unavailable…
TTN always worked flawlessly, WiFi/GNSS position fixes show-up on the Locator map nicely.
