I cloned and built the moodleapp (integration as well as master branch) by using npm setup and npm run prod:android.
When I connect with any moodle instance (e.g. school.moodledemo.net) I get the error when accessing content in a course
Http failure response for (unknown url): 0 Unknown error
The moodleapp from play store works fine.
I tested with emulator as well as with a real device by building a release apk.
This seems to be a CORS problem, but what I am asking myself: Where is the difference between the play store app and the github app?
What changes do I have to make?
