Health sharing data with Noom

In the Noom app, I have allowed data sharing with Health. It’s working fine. However, Noom can’t access the data from Health. When I go into the Health app for data sources and access, the screen is greyed out. The field for Apps Allowed To Read Data contains the word None, also greyed out. This problem seems to be at least 18 months old, judging by the date on the last question on the subject. Please don’t tell me to contact Noom!
