Live view not working on mobile data in app but does via Alexa

Recently purchased the Ring Pro 2 which has been great, but I have an issue that I cannot work out after a lot of troubleshooting. Live view works via the app when connected to Wi-Fi but not when I’m using mobile data on my phone but it does work using mobile data if I access it using the Alexa app skill, strangely live view on mobile data does work on my wife’s phone as a ‘shared user’ so the stream is definitely accessible remotely but for some reason not via my Ring app.I’m using IOS and the app does have access to network, mobile data etcAny ideas as to what could be blocking it? Thanks in advance
