An app need to be really bad to trigger me spending time writing a review. After uploading all passport scans for my family and entering Hotel address for my US stay, the app simply got no response when I press [continue]. I restarted from beginning multiple times, waiting document upload and verify again and again, still the same. Finally in various tries, I found it was caused by the ‘ in the Hotel name. However, after passing this, and continue with remaining steps and last step, the final result is, checkin still cannot be proceeded with no reason given and asked me to go to airport. What a waste of time.
