Problems with Logitac keybard with iPad Pro

I Have been using the Logitec keyboard with my iPad Pro for some time, and have this very annoying problem. When I write, the keys cannot keep track with my speed. Lots of keystrokes does not get registered, so words miss letters, or the space comes in the middle of next word etc. I have to correct everything I write, and this slows me down.

I Don´t have til write vety fast either, just normal speed. Anyone else have this problem, or has any idea of a solution?
