I'm a new tester, today I tried to enter .4 ounces of something and the app wouldn't take it. Eventually I entered 0.4 and it worked.
Can you update to the latest beta build and check that again? I believe we fixed it in the most recent build
As always, any and all postings here are covered by our T&Cs:
I spent about an hour last night trying to get the app to work, I kept getting a blank diary page, then health kit errors, etc. etc. At 10:30 I deleted 285 and reinstalled the old version. When the next release comes out I'll re-test this item.
It's working now.
