Intercom not showing TALK button on iPhone but can speak via Alexa

Hi - my Ring Intercom isn’t showing TALK button on iPhone, although I can speak only via Alexa - UNLOCK-is working fine.I have Bell 801 handset

Hi @David22. Could you provide us a screenshot of the Ring App, where the button is not visible as well as your current version of your Ring App and the iOS system? We look forward to hearing from you.
