When connecting the second MQTT client to the Thingspeak channel, the connection is first bursting. What could be the reason? Or is it a limitation of a free license?

If you are using the same triplet of clientid, username and password on multiple devices,only the last connected device will stay connected.
You need a unique combination of clientid, username and password for each device making an mqtt connection.

Thank you for the hint! I added a new MQTT device in the Devices section, linking to the same channel Thingspeak and received new client ID, Username and Password. Now it works with two customers as expected.
