Problem:
If you are receiving your first phone call via the native iOS call screen while microphone permissions for the FYI app have been turned on in the settings, other participants on the call won't be able to hear your audio.
Workaround:
When you are in the call window, simply click on the FYI logo button to open the FYI app. A popup will then appear to request microphone permissions. Granting these permissions will resolve the issue.
