For anyone who is searching as of today June 6, 2021. The RingCentral App does NOT work. And error comes up saying "App update required. RingCentral needs to be updated to the latest version from the App Store in order for new features to work properly". Pressing OK brings you to the App Store and the only option is OPEN and there starts the loop where it opens RingCentral and then sends you back to the App Store.
You can receive calls and join a RingCentral meeting. But anything that require initiating anything from the App does not work.
