Doorbell live view fails to open with dual SIM iPhone 14

Hi. With my iPhone 14 live wiev fails or it takes a very long time to start a live view session. The person who pressed the bell has gone before I connected! I've seen a few threads dealing with dual SIM and IPv6. But on my iPhone 14 it is not possible to disable IPv6. (I have no MAC) The problem * The error only applies to 4G/5G * WIFI works fine * The error only applies when both mobile networks (SIM cards) are activated, I deactivate one mobile network and everything works fine. (It doesn't matter which line I disable) Is there a workorund? (until RING fix the APP) BR Johan, Sweden
