No, the Problem is that on both operating systems there is no export/import from file option. There should not be the need to rely on cloud services

Not on iOS and there is no way to load an icloud backup into the android app / google drive

There is no alternative for whatsapp, and transfering whatsapp chats somehow only works from android 12 (the device had android 11)

I helped a Friend move to android a week ago and it is just a nightmare. It is just frustrating since there is not a single guide you can use. Everythin works only from android version X to Y and your phone has android Z and does not seem to get updated anymore even tough it is just one year old. And even if you have the right android Version you are unlikely to be able to follow anything step by step, since everything looks different with every manufacturer.

iOS with its walled garden ecosystem is certainly not great, but Android is just awfull and not an alternative
