I have English/US.
I don't know if this matters, but I initially downloaded the app on WM10 and added ~10-15 passwords. Then downloaded the app on Win 8 desktop and added ~30-40 more logins. After that I was able to use the app on the phone for few days. But since last 2-3 days the app on the phone has been crashing. the app on the desktop still works great. Is it crashing because the mobile app needs to be *purchased*, but if so I still cannot get in to purchase it.
After uninstalling and reinstalling, I launch the app and it asks me if I'm a new user or returning user. I select the option to restore data from OneDrive, and app crashes immediately after selecting OneDrive link.
Thanks Anshu for your quick reply.
