ZaggFolio case for iPad Air... since the 8.1.1 update, I seem to have more trouble with text input. Autocorrect never worked but now even spellcheck seems non-functional. Misspelled text is not even highlighted anymore. The iPad will also lock up from time to time and the only way to get response back is to turn off the keyboard until the bluetooth indicator goes out, then turn it back on. Anyone else having issues?
