I have used IOS move android to ios app from my android mobile. it's has already a Android 12 mobile. All the backup preparation done successful including Message, Contacts, Photos and WhatsApp also. When I have installed the WhatsApp on IOS device it has starts the import option to restore chats histories but at sudden stuck at 40%, Even multiple retry attempts could not able to solve it. Don't know what should I do now. It's really frustrating experience with ios 16.5.
