Not receiving notifications to Ring app

I have been using a Ring doorbell2 for 10 days with no problems until yesterday. I am not receiving notifications on the Ring App in my phone unless movement is at my front door, nothing for the zone I have created. My RSSI is -58 and I assume it should work and has done before yesterday. The only change was we added a chime but this shouldn’t affect my phone notifications. I have been through troubleshooting and changed all settings but nothing works. How can this be resolved?
