Posted this in another thread but I'll put it here too:
I'm having the same problem. Whenever my phone tries to autocorrect a word with some form of punctuation ("im" to "I'm) it freezes up and resprings. This also happens if it tries to autocorrect and some form of punctuation directly follows the word ("Hi katie" to "Hi Katie,").
My first thought was to go to the "FAQ/Support" thing in the app and see if there was an easy fix; there wasn't. Down at the bottom of the page, however, is the option to turn on "System Logs" (or something similar to that) which monitors the app and sees where something is messing up. When I turn that feature on, recreate the problem, and try to send the log to their customer support an error message pops up telling me that "system logs" needs to be turned on first (I'm assuming my phone crashing kills that process).
I've emailed Intelliborn customer support twice but I haven't gotten a response.
