I did some tests Roco. I’m using it since the first v5 rc’s.  
It now works different, compared to the earlier fw versions so it seems?  
Normal ack:

Reversed ack:

I now have started a test flow, ignored the push ack, and going to wait (24hrs) for what happens next.  
_Curious if there’s a time limit at some point_.

[Last time I checked](https://community.homey.app/t/enhance-the-localisation-option/45865/16), the flow stayed on hold for 1 hour.
