The updated app is nicer looking than the old but many features are gone. For example I can no longer access settings, prices or ride history. There is now a grayed out icon, which, upon pressing informs the user that this 'feature is coming soon'. If you are going to release an unfinished product inform the user first and let them opt into an alpha/beta rather than forcing them to update. Also, it is illegal in Sweden to not show prices for your services.

Beware: the app sometimes hangs for no reason and you can't activate a scooter. Neither by scanning, nor by entering the digits. First the support tells you to walk 20 minutes to the next one (because the one you try to scan they say is broken, I bet without even checking), and after the next one doesn't work as well, they ask you to reinstall the app. After that, it works. I wonder why this doesn't happen with other apps.

ok now I can register. I found some bugs in registration flow. You should allow first name and last name to 2 characters. It's still valid info. And please give users some instructions what's wrong. Saying general error with server doesn't really mean that much. Last but not least, I hope you would check rating more. If it's a known issue, maybe reply to comment would help you improve rating
