can’t merge calls
hi. my friends and i would like to have a 3 way call (iphone 7, iphone 8 and iphone XS max) and none of us seem to be able to merge calls. each of us has called one person and can add another person to the call but the first person would be put on hold. whenever we press the merge calls button nothing happens. please help. thanks
iPhone XS Max, iOS 13
