Speaker Phone not working on Iphone 6 when using RingCentral App.

Problem: My speaker phone works fine on a regular call, but not when I use the Ring Central App. Also the microphone works if I'm not on speaker. I'm a user on a company license. Troubleshooting Steps: My phone is up to date, app is up to date. I have deleted the app and re-downloaded it. I have restarted my phone after re-downloading the app. Speakerphone works fine on my ringcentral desk phone. (I don't know if that's relevant or not) Microphone is enabled in Ring Central App settings
