Syncing Beta to Strava

Hi, I signed up to the beta site yesterday and get a page not found error when syncing to Strava. When I go on the normal (non-beta) site, it syncs perfectly. Anyone else with the same kind of issues?

When trying it on another machine, I get - {“message”:“Bad Request”,“errors”:[{“resource”:“Application”,“field”:“redirect_uri”,“code”:“invalid”}]}

Beta will be decommissioned very soon. Use this site.
