iPad Pro Fetching mail problem?

Two mornings in a row my 9.7 iPP does not seem to be fetching mail every 15 minutes.

When I first check for mail, it says at the bottom, briefly, "Mail last checked yesterday", then it checks for mail.

Is there a setting I am missing. Never had this problem before. Maybe it is checking for mail but just not updating the screen?

 

Hmmmm. Never seen this before, hope it corrects itself as when at home I may leave my iPhone in the bedroom and depend on iPad in the living room to sound off when I get an email. I do not think I have ever seen it say "Mail last checked yesterday" before.

Thanks for your reply.

Update: Just looked at my iPhone and it say mail last checked at 5:09 and it is 6:22!

Got to be the last update for it to be happening on my phone, too!

Never had this happen to me, know notice on my 9.7 iPP and 6S+

 

Still having the same problem now with BOTH my new iPad Pro 9.7 tablets.

 

Mine comes and goes for both iPad and even my iPhone.
