Motion notifications delay.. if at all

Why are notifications from my ring doorbell delayed for anything up to a minute and longer on my android  phone when my echo show notifies instantly . They're both on the same network and no vpns involved.Its beyond annoying as I bought the thing so I'd be alerted anywhere in the house and garden,I even bought an echo dot to install in my green house and can't get any notifications on it at all even though it's connected to the same network and it works fine responding to Alexa and playing music etc .These problems seem to be widespread and as far as I can see ring hasn't done much to address the problem.Maybe time to bin it and buy something that actually works how I expect it to.
