I noticed that the Connect app wasn't showing as a Source in the Health app. After finding other people having the same issue, I discovered a solution was to log out, uninstall Connect, reinstall it, create a New user, and say you're only using it to connect to the Health app, at which point it finally shows up as a source, and then you can log out and log back in as your real Connection account.
This worked in as much as Connect now shows as a Source, with all of the permission flags enabled.
However, after doing a ride this morning, and keeping the app open and doing a sync, no activity was posted to the Health app.
What am I doing wrong?
I tried to add a manual activity to test it again, and the Connect app just sat there with a running man icon for 5 minutes, being unresponsive, as it often seems to be.
