Noticed this, not sure if it was because of Blend or rather the network.
Had a friend call me, initially the caller ID was showing up fine with his profile picture and number recognized to the contact showing the name, however that call was a network fault, all we heard was popping noise.
I then connected my phone to Blend and Link via Wi-Fi to transfer some stuff, and he called me again after I called him back without pickup. This time, however, the contact was not matched to the name and came in as "unrecognized caller" though the number was the same.
