I hope someone can help me, it´s been 4 days trying to make this work.

I own an iPhone 11 Pro and have just migrated to an S24 Ultra 1TB.

I did it all correctly according to Samsung instructions about transferring Whatsapp chat data from my iPhone to S24Ultra, including doing the fabric restore and installing latest version of Smart Switch, Whatsapp, using cable, same WIFI network, turning off iMessage an Facetime, etc).

Well, I realized that after finishing the process, most whatsapp chats are not being displayed - even though I can find them when I search for a specific contact -. Why´s that? Can´t I have them all displayed as before, without having to send a message to the chat contact? Only group chats are being displayed.

The other problem is that I´m an admin in some whatsapp groups, but after transferring chats from iPhone, when I open these whatsapp groups in S24Ultra, it simply shows as I just joined that group, losing all the group history and past messages, media, etc.

My next attempt now is to backup my Whatsapp chat (55GB) in iPhone through iCloud (200GB storage), delete whatsapp from iPhone, reinstall it using this backup and only after that doing the Whatsapp Smart Switch Transfer,  and restore the chats in S24.

But each attempt take hours, so anyone could me help solve this?

Thank you.
