Weird bug that I haven’t found much about online - hoping someone here has faced the same and solved it?

I used WhatsApp’s transfer functionality to transfer my entire chat history from my old to new iPhone (15 Pro Max).

The transfer worked fine but since I transferred, I can’t see any messages sent or received after the transfer in my chats with people.

When someone texts me, I see the text in the main page with all the Chats, but when I open any chat it’s “frozen” at the point that the transfer completed.

When I text someone, I see the message as sent in the chat. But then when I return to the chat, it’s reset to the status as of the completion of the transfer.

Did anyone else have the same? Any way to fix it?
