I did have trouble typing after the arabic. It was inserting characters in the middle of the arabic text. I have never tried typing in a right-to-left language on iOS but I’m assuming that isn’t normal? Or maybe it is because my keyboard is still English which is left-to-right.

Typing in two languages that are following opposite directions is complicated and it’s not possible to change from one to another on different platforms or apps. That’s why I usually type on notes, then copy and paste the text. Sometimes the « posting space » on different relays does not keep the format of the pasted text tho, that’s why the Arabic comes out wrong.
