McDonalds app not working

Iswear

So I recently installed graphene OS so really a newbie.
I so far found out that banking apps seem to have problems, but I can live with that,since I can still do it on my PC.
But I just realized that my McDonalds app isn't working either. And I don't want to come across like a fat bastard, but I'm really attached to my horrendous amount of bonus points I have.
so is there any way to solve this issue?

As far as I'm aware, McDonalds does integrity checks that GrapheneOS can't pass, unfortunately.

Iswear The McDonalds app is known to enforce something called Google Play Integrity in strong mode, which means that the app disallows being run on anything but an OS that has been certified by Google – which GrapheneOS is not. For an OS to become certified by Google, it needs to give deep system integration to certain Google services. There's nothing GrapheneOS users can do to bypass the Play Integrity enforcement other than to try to convince McDonalds to allow GrapheneOS, which they can do by using attestation.

Iswear Which app are you trying specifically? There are multiple McDonalds apps for different countries.

McDonalds App here in Germany works with Graphene OS without any Problem....

phone-company Are you using the German version of the app? The "standard" version is named McDonald's, but there is a German one named "McDonald's Deutschland".

I can confirm that here in Italy it doesn't work. I'm using the "McDonald's" app.

Fundamental_Physics yes "McDonald's Deutschland" is the one i tested.

Seems to run OK with the UK version

I was curious about the app and I was able to sign up for an account on the "McDonald's" app by "McDonalds USA, LLC"
