So funny, I talked to support last week and was initially told they had never heard of this issue and it’s my personal WiFi. Then, I sent them this thread, so they said it was a Verizon issue. Verizon says nope. Then, Apple told me it was because the OS on my laptop was Catalina and not Big Sur (... how that affects my phone, which has never been connected to my computer till now, could not be explained). Updated everything per their directions and still dropping calls every 3 to 5 minutes. This update cannot come soon enough — particularly with so many people relying on WiFi calling while working from home during the pandemic.
Hey, Apple, why don’t you at least comment on this thread and let us know you’re working on it???
