Fibaro and Tuya App intalled without Devices

I have installed the Fibaro and Tuya app under Homey Pro. Although the Fibaro and Tuya networks have devices, I get the message that no devices are installed. Instead, I get the message that Fibaro or Tuya app will be installed shortly, but nothing happens. What am I doing wrong?

Just installing an apps does nothing, you have to add your devices to Homey explicitly.
