Ring door 2 huawei P20 and iphone7 not working

Hi there, Just installed a new ring 2. On the p20 there is no two way audio possible; i can just hear from my doorbell to my phone and not possible to talk to the doorbell How to solve this? On the iphone; when a ring comes in i can answer this. Although it goes instantly to fullscreen with just the speaker muted symbol in the right bottom corner. I can tap that one and hear the person at the doorbell but i can not talk back When i rotate my phone the live windows will get smaller and; instantly there is the mic button shows, but it is muted. When i unmute this the 2 way audio works fine. I was hoping to find the same on the Huawei, but it isnt there. Both is very anoying. How to solve this?
