I"m trying to get this working right now:
There is a coaching app on my phone, that reads activity data (steps) from google health connect or ist least trying to..
I understand that this should work on my profile without Google Sandbox because health connect api is part of the base AOSP / GrapheneOS right?
I've tried some step counting apps from f-droid that hav. "activity" permission, but the data doesn't reach the coaching app via health connect: It always raeds zero.
I think all permissions are set correctly after checking several times...
Am i missing something?
