Unfortunately, the issue you are seeing is not a problem with the keyboard, but TheBrain app itself. We've received a few reports of this latest update freezing at the splash screen. Can you delete TheBrain for iOS and then re-install from the link in TestFlight? Does that resolve it for you?
If not, can you send an email to email@example.com and we will help you further.Cheers, Sean
