I subscribe to around fifteen YouTube channels, most of which are set to: Send me all notifications for this channel
 
This was working fine up until around two weeks ago since when I have received no notifications whatsoever from any of these channels. I've checked each channel in turn, and all of them have published at least one new YouTube video in that time.
 
I've gone in to Manage Subscriptions in YouTube and made certain that I have Send me all notifications for this channel checked. I've even unchecked the option and then rechecked it again to see if this helps but to no avail.
 
I'd really appreciate any advice which can help me restore the email notifications I was receiving perfectly fine up until around a couple of week ago.

Are you sure you're not getting the emails or are they being diverted by well-meaning spam filters?  I had that a while back where a lot of my usual emails stopped and I found that they were all going to either a spam folder or a junk folder.  I had to mark them as "not junk" to get things back to normal.

 
Thanks Craig, but I checked that mate. I've just completely drifted off the radar for some reason. I tried posting the same question in the YouTube forums and someone else said the same thing happened to him.
 
I'm beginning to think it might be something to do with Google as they've somehow managed to swap my long-used Google/YouTube account email to a throwaway gmail address I used for a one-off registration elsewhere. Now I've had to set up the new email they've 'accidentally' assigned to my account to forward everything to my usual address. It will be interesting to see if that sorts it out.
 
 

Straummy has more email accounts than Bobby had logins.

And his emails are just about as confused as...  nah, too easy.

I need to have so many because you big boys like to steel them off me.

I wonder if he wants your LGBTQIA Atheist avatar too!
