I use https://organicmaps.app/.
On other Androids, Organic Maps can open Google Maps links by default.
On GrapheneOS, under "Settings > Apps > Organic > Open by default", there are only two verified links: www.openstreetmap.org and ge0.me.
Beneath, there is a button "+ Add link". But it's greyed out and clicking it does nothing.
I tried app link verification manually, but unsuccessfully:
$ adb shell pm verify-app-links --re-verify app.organicmaps
$ adb shell pm get-app-links app.organicmaps
app.organicmaps:
ID: [UUID redacted]
Signatures: [Hash redacted]
Domain verification state:
omaps.app: verified
How can I open Google Maps links with Organic Maps on GrapheneOS?
