I bought the Huawei p 40 lite and transferred all the data and apps from my old cell phone, now I only have the problem that I don't get all the Whatsapp messages on the new cell phone but mainly on my old one and I don't know what to do.
I do not know if it is maybe that the new cell phone has no google services… But I was still able to transfer WhatsApp
Did you also transfer the number? As far as I know WhatsApp is tied to phone number
