Hey, Iv’e notice a lot of people don’t seem to know this, but there are simple apps that can create a separate environment in your own phone. Kind of how a VM (Virtual Machine) works in a computer.
If you are are gonna play two accounts in the same device, this is defiantly the best way to go about it.
ParallelSpace - https://apkpure.com/parallel-space-multi-accounts/com.lbe.parallel.intl
VirtualXposed - https://www.malavida.com/en/soft/virtualxposed/android/#gref
I prefer virtualX but PS is much easier to use and safer in a way. I also heard virtualX works better if your device is rooted, so if you don’t have a rooted phone, go for the first one.
Granted I haven’t used the IOS apps myself, just from a quick search seems these are the best two.
P.S. If you ever contact support and they ask you if you access different accounts in the same device, you are better off saying “no” than trying to explain them how a virtual space works.
