Doorbell no longer ringing on my phone when pressed

I've had the ring for a couple of years now and was initially impressed. I even stayed when they recently hiked up the price (even without being told) but for a few months now, no actual ring on my phone when someone pressws the bell, only a standard notification that there's activity detected, which could be anyone walking within the 'zone'  Looking into settings it seems this feature is now locked and requires an upgrade from the basic plan to now have rhis feature. It was the main reason i bought the ring! Can somebody please confirm this? If so, this is the last straw and I will be cancelling and going elsewhere like lots have. Selling us cheap (ish) products then forcing us to pay more and more and upgrade. Disgusting.
