Notifications delay

Hi there. Last two weeks i am not getting notifications on time. It getting delayed 15minutes some time longer time. I tried everything to fix but still going through same problem. Apprentice your help . Thank you

I had the same problem it drove mad then I found out if you logged out of the app, which I didn’t realise you could do, then log back in again it was supposed to resolve the problem and touch wood it seemed to work for me but I suppose all phones have their quirks.

When that happened to me I rebooted my phone. it’s been fine since.
