Don't Die App Updates

After choosing a profile picture and clicking continue i am getting an error

Adding an option to change measurement units from pounds (lb) to kilograms (kg) For example, when adding Biomarkers > Weight > lbs. The best solution would be to include a setting under Settings > Change Measurement Units for the entire app. This way, when viewing other people's stats, they will automatically be converted to kilograms or pounds, depending on the user's preference.

Get a “code 6” - we ran into an issue, please try again later when trying to choose privacy seatings during account set up. This was the error message I got for adding profile photo for a few days and now the next section is causing the same issue. Screenshot attached

Get Alert: We ran into an issue. Please try again later. Code:6

After changing my username, the change looked as though it was saved, but I was left on the editing page. I would think I would have been automatically navigated back to the Settings page where I could check.
