You just updated to 2.3.4.119?
That was an issue in 2.3.4.118, I expected it to be fixed in .119, but looks like not if you're on .119.
Please confirm your current hub FW version, .118 or .119.
I assume you didn't do anything, just looked at your rules and saw the "Broken" notice like below?
.118 discussion here:
