I have a friend who has iPhone and iPad, no Mac. She has some Contacts in Yahoo and some in iCloud. Her WhatsApp only sees those in iCloud. As far as I can see the only solution, and is logical anyway, is to consolidate Contacts on iCloud. Without a Mac this seems difficult?
The only way I can find to do this, but seems very dated/cumbersome, is to set up a temporary user account on a Mac. Export Yahoo Contacts as vCards and import into iCloud.
I will have to check to see if she can export in bulk from her webmail account rather than one card at a time. I don't think you can export in bulk from iPad Contacts?
Thanks Mick. The desktop site comes up on the iPad OK but I tried importing a bundle of three cards but it only loaded the first one. I'll keep playing.
