02/4/2021 I avoided upgrade to IOS 14 because of reported issues, but last week when Apple on National news broadcasts highly recommended upgrading due to serious security breaches, i went ahead. Wished I had not. When on WiFi phone calls my microphone cuts in and out. When on cell network it's just fine. We checked mics and did all the recommended checks and all are fine. Then i found this forum and see I am not alone. This is definitely an IOS issue and needs to be resolved quickly as getting a new phone (such as I 12) is not an option as issues there as well.
