Since yesterday June 9, 2021 @2100Z the MQTT API is no longer include any topics to the messages it’s publishing. Just its value.
Nothing has changed on our side. These have been production units for years now.
Network is not at fault. Devices are connected from all over the world.
The MQTT message broker is 100% operational and works fine with devices unrelated to Particle.io
Not a device issue, we have both Argon and Photon and all running either 1.5 or 2.X FW versions without any issues until then.
Anyone else witnessing the same behavior ?
