Missing + button since iOS 11 – Microsoft HealthVault Review

I have been keeping my blood pressure records in this app for over 4 years. It worked flawlessly until iOS 11. Now there no ability to add records because that functionality has disappeared. I reported to Microsoft and exchanged some emails. No progress! My only option has been to use the browser on my Mac or use an old iPhone running iOS 7.
