At work I have to use an iPad and since I work in a french speaking environment as a non-french speaker, I am mixing my mother tongue german with english and a bit of french - on Android, no problem, just tell the Auto-Correct that you are using these three languages and you're good to go.
But Apple (just very recently) gives me the availability to choose just two languages for auto-correct, and of course I very often are in the wrong mode (ge<>en, en<>fr, ge<>fr) and some words get corrected wrongfully.
The whole typing experience is horrible as an Android User for 13 years and it's nice to see that it's not just me.
