I, too, am running into the multi-notification issue but just updated to the latest so I'd expect that to resolve. I do however have another behavior that is plaguing me.
I've got my parity check scheduled from 12:30am - 7:30am with it pausing for updates, backups and mover which occur at 3am, 4am and 6am respectively. What I can't figure out is the parity check pauses at 4am and does not resume until the next day at 12:30am. This feels like a config issue and maybe not a bug. Anyone have any ideas? I can provide the diagnostics if it would help.
