Your subs can double check their bell settings for the channel & make sure they've opted-in to receive all notifications & not just "occassional". After that, make sure their app & device settings are turned on: https://goo.gl/UCRcbp . Let us know if things still aren't working!
Just to confirm, are your subscribers not receiving notifications or are they delayed? Also, mind sharing screenshots and more details from your subs, we'll take a look!
