@Caseda Thanks. for the afford.
Strange that the tags not a Fibaro item is.
Because at other flow cards the tags still working?
To test this I did make a flow with Fibara RGWB cards. At some cards I added a tag and at some ones with hand settings.
Beside this I did add a papertrail card (To test tags on other app then Fibaro) to log adding a tag at this card (The same as used in the RGBW card)
All cards did run except the RGBW ones with a tag added.
I realy do believe that it has something to do with the Fibaro app
