You have to set all your app which use widget in Permissions/Autorun and it Will fix it.Same problem here. Widgets don't work correctly (with Nova Launcher) on newest firmware (6.9.22). 'Power Toggles', for example are working only until first screen turnoff, afterwards they don't toggle anymore... ;-) All ok with previous firmware versions.
