Autocorrect working unstable in IOS

I am trying to implement autocorrect in my current application i add the directive as described in:

where it states that autocorrect=“on” to the ion-textarea (I want the red dots underneath the incorrect word). I deploy this to the device and it works the first time i launch the app, but once i kill the app from the memory and reopen and autocorrect never shows up anymore.

I created a new blank ionic project added ion-textareas with autocorrect and i was not able to see it working.

How can i make it work and make it constant?

Best regards
