Thanks for the confirmation, Stan!
It sounds like the hotfix has resolved the originally reported issue of the states getting out of sync (on color control tiles) when controlled by a rule.
Regarding the ! showing for a moment after manually controlling things by tapping a tile… that typically indicates that the device is a tick slow to report it’s status back to SharpTools. With the introduction of Instant Switches, the tile will immediately reflect the expected state for switch type tiles.
After the light is toggled, it waits a few seconds and then verifies that the status shown on the tile matches what is reported by the hub. If the hub hasn’t reported back the state, then it will show the warning. It sounds like in your case, the state update is a tad slow, so it shows the warning icon briefly until it gets the proper event update.
