More iPhone microphone issues!

Hey guys & girls hope you can help. Recently my Ring app no longer allows me to hold a conversation through the ring 2 doorbell. I can hear them but they cannot hear me. I’ve checked my privacy setting for allowing ring access to the microphone however ring is not listed. Checked my wife’s phone and it is (works fine on her phone) I’ve tried reinstalling and re logging in on the app still no solution! Any ideas? Thanks
