It, uhm, works with a keyboard. While touch-based UX is nearly flawless, there are some weird delays, e.g. when switching keyboard layout (you may not know of this problem if your language uses Latin script) -- very annoying since it tends to swallow characters.
Uhm, I have the iPad Pro 12" and that "magic" Apple keyboard cover (that crazy expensive one) and use Japanese, English, German as my input languages, switching often. Zero lag whatsoever.
Good, maybe it was related to the Logitech keyboard. How do you switch layouts, cmd+space? It opened a small window that blocked all input until it auto-closed half a second later.
It has a dedicated key with a globe symbol in the lower left corner. I know what pop-up you are talking about, but that's non-input-blocking, i.e. the language is active when you press the button, and you can continue typing without any wait.
It's possible that your iPad is not performant enough to both render that popup and and deal with keystrokes at the same time. I'd recommend the Pro iPads for any kind of serious work.
That was Pro 10.5 2017, it’s still a very fast device. The Logitech keyboard didn’t have this dedicated button and I last used it like a year ago, so I’m glad the issue is nonexistent now with proper hardware. Thanks for the response.
