Appium is not suitable for all types of tests. There is a particular scenario that will make your tests more difficult to write: data exchange. I already said it but I will repeat the same thing because it is very important: Appium and WebDriver are designed to automate stuff… not to exchange data with them. So what if we need to exchange information with our app during tests?

Should we give up on Appium and write our tests manually for each platform? I am not saying this, but there are cases where you should consider this option (not nice I know, but if the effort of writing tests for Appium is higher than the benefits, then just throw Appium away).

Appium is very nice because it will let you write tests once for all platforms instead of writing as many tests as the number of platforms you need to support. So if you need to exchange data with your app while testing it and this data flow is the same for all platforms, then you should probably keep on using Appium and find a way to write a layer on top of it to handle data. Depending on your needs this might take time, but, in my experience, it is really worth it.
