Would like the facility on mobile that desktop and web app has to create both private and group ephemeral voice rooms. As it currently is the mobile user can join a call/room when invited but can not initiate a conversation. A desktop user can start a call to another member from the member profile popup, a mobile user can not. Being able to talk to other members even while on the move is a great feature for building a socially interactive and cohesive community. Holding private calls (between 2 people) via Heartbeat, rather than having to exchange phone numbers (expensive for international) or use some other app like Whatsapp or Google Meets, also fits the philosophy of one place for everything. The missing "Start Call" button does seem like an oversight rather than a deliberate design choice. Hope that it can be added sooner rather than later.
