Alexa App - cannot create routines although devices are listed


although i tried to do everything rule and logic based in openhab i need to create an alexa routine for my doorbell.
unfortunately there is a huge delay when the doorbell is pressed until my echo devices play an alarm sound (around 7-8 seconds).
Now i got the idea to do this directly in the alexa app and i hope it is faster.

However i cannot create a routine. The app reports “no smart home devices found” - there are clearly all of my items listed in the app and they are also reacting (light on/off …).

I tried deleting all items and let alexa rediscover them again but the issue remains.
