Working from make.powerapps.com in a solution I made a approval flow. Testing with a time-out setting of 10" (PT10S) all worked fine.
After changing the time out setting to P3D or PT72H the value changed, was saved but the flow keeps using the 10" value.
I opened the flow in make.powerautomate.com to have the new designer and published the flow but still no succes.
Even Making a copy of the flow and creating a new connection does not did the trick.
Someone any other ideas?
