OAuth error when linking my account to third party app

I’m trying to login to the Organic Maps app on Android with my OSM account, but it’s failing silently after I click the authorize button on the confirmation page. No error is displayed on the page, but in the browser console I see this error:

Failed to launch 'om://oauth2/osm/callback?code=' because the scheme does not have a registered handler.

I’ve removed the code string myself but happy to provide it privately if useful. I tried to authorize in Brave and Vanadium on Android, and Edge and Firefox on Windows 11, with the same result.

My OSM account is old and not very active, if that makes a difference.

This is not an issue with OSM, it’s a problem of the Organic Maps app. Looks like the app failed to register a custom URL handler for the om:// URL scheme, so the browser doesn’t know it should pass it on to the OM app. Try deleting and reinstalling the app.
