Help! Watched thread emails and notifications

Hello to the powers that be,
I seem to be getting email notifications from watched threads sporadically (some don't come through at all) and some over 24hrs after the posts are made.
I just received 2 emails today which were from posts yesterday and there have been several replies since which I received no emails for.
When viewing the forum I do seem to get the little bell at the top of the page showing replies to threads but some of those seem to be missing as well. Not a huge problem but I don't want to appear rude if I'm not replying to posts because I don't know they've happened.

I thought the odd behaviour may be of interest to you Adminy types (sorry if its added work to check out).

TIA

I think Chris has been on this today..

Ah, looks like it may be related for sure. Weirdly I got the notification for your reply to this at the exact same time as a notification for a post at 10am this morning.
So they are coming through just without rhyme or reason.

It'll be clearing a backlog

Hell of a "comfort break"!!!

As always, thanks to ALL the team for ALL their efforts in keeping the place running in the face of adversity.

(And YES, I'm only grovelling to get an extension on my FREE membership!)

Yes, thanks indeed! It all seems to be back to normal today.
