Ring not sending notfiactions!

I know I am not the first person to raise this issue!! Why does the Ring Doorbell 3 not always notify me when there is motion or even if someone rings the bell!!! This really does defect the whole object of the device!!!My wife and myself have both the same smart phones, I am the account holder and she is the guest but she will always get notifications but as for me hit a vey mucah a hit or miss if I get notifications if any!!!I have tried all the solutions that have been posted for example clearing the data from the app, reinstalling the app, reseting the phone, turnning notifications off then on and the restarting the phone. All have the same result, very sparadic alerts if any!!!So this might have to be return as the product as it is not fit for purpous unsless there is a soultion!!
