Scene doesn't disable timer

I have a manual scene, say A, that should disable three other scenes, B, C, D, where there are delays acting on devices once an alarm is detected
Although the scenes which should be disabled are indeed disabled the action triggered by scenes B, C &D do continues to take place and although these scenes are disabled action eventually takes place as if these scenes weren’t disabled
I think it is a general bug related to the action of scenes which should reset ALSO all the delays invoked in the scenes b, C &D
Any suggestion?
Who should I eventually report this bug?

iHost or App, would you mind providing the version number and logs via help center?
